Main trade-off
Line 6 HX Stomp
Extra foot control can consume the shared EXP/FS connection or require a separate MIDI controller.
Head-to-head
Choose HX Stomp when it fits among existing pedals and three switches cover the actual set. Choose HX Stomp XL when more direct foot actions, a fourth snapshot or hands-free editing would replace an external controller. Both have the same processing power and neither includes an expression treadle. Count the complete rig before deciding which is smaller.
Before you choose
Suppose the guitar travels by bus, but the set needs separate effect toggles, a tuner and continuous volume. HX Stomp is compact on its own. Once an external switch or MIDI controller and an expression pedal are added, their cables and placement become part of what gets carried. XL can replace some switch hardware, but still needs an expression pedal for continuous control. Choose Stomp when the existing board already supplies those controls. Choose XL when its onboard switches remove equipment you would otherwise buy. Measure that complete arrangement instead of comparing bare enclosures.
What this is based on
Limited travel space plus a specific live control list crossed with switch counts and separately required expression. No unmeasured total-size or setup-time saving is claimed.

Main trade-off
The larger body adds control access, with the same DSP limit and no expression treadle.

HX Stomp vs HX Stomp XL for a small pedalboard and live changes. Compare the complete controller setup, snapshot limits and the recording features they share.
The same player can choose the same processing platform in a compact three-switch unit or a larger eight-switch board. The buying decision concerns control access and the complete packed rig, rather than an assumed tone or processing upgrade.
Winner by situation
Stomp can fill the remaining processing role without duplicating controls already owned.
XL supplies four. Stomp supplies three and needs a different arrangement.
Both use the same processing power. Extra switches do not address that constraint.
The essential USB recording route is shared, so XL needs another reason to occupy the space.

A player using clean, rhythm, lead and a fourth variation can keep four snapshots in one XL preset. Stomp provides three. That can make XL useful when each section changes existing block states or parameters and should stay within one preset. However, both use the same processing power. If the problem is fitting another demanding amp or effect into the sound, XL is not the upgrade that fixes it. First separate the need for another saved state from the need for more DSP. That distinction can prevent paying for extra switches while keeping the original limitation.
Four recurring musical states versus a processing-capacity problem crossed with snapshot count and explicit DSP parity. Snapshot changes do not imply unrestricted replacement of loaded models.
Someone who records most evenings and plays out occasionally already gets processed and dry USB recording from HX Stomp. XL does not need to be bought simply to keep a clean performance for later tone changes. Its stronger case appears during the rehearsal: hands-free edits and more direct switches can reduce the need to stop holding the guitar to reach controls. Choose around the part of the week that creates the real obstacle. If the unit stays at a desk and a prepared three-switch set covers the occasional outing, Stomp retains the recording route without the extra board width.
Mostly seated computer recording plus occasional live use crossed with shared USB capability and distinct foot-control access. No latency, tone-quality or ergonomic-health ranking is inferred.

Line 6, HX Stomp
Keep a compact processor inside an existing board when three onboard actions and current controllers are enough.
Line 6, HX Stomp XL
Keep more changes under separate switches and use four snapshots within a preset.
Meaningful differences
| What changes | Line 6 HX Stomp | Line 6 HX Stomp XL | Why it matters |
|---|---|---|---|
| A song needs more direct actions | Three switches and three snapshots. | Eight switches and four snapshots. | Count the actions required at the same moment, including tuning or bank changes. |
| Add more effects to the same sound | Up to eight processing blocks within DSP limits. | Same processing power and eight-block limit. | XL does not rescue a preset that runs out of processing capacity. |
| Adjust a sound with the guitar in hand | Onboard knobs or configured external control. | Hands-free Pedal Edit and six-switch looper access. | XL can make those jobs available without another controller. |
| Keep a take for later tone changes | Processed and dry USB paths with reamping. | Same documented recording platform. | Computer recording alone does not justify the larger control surface. |
What you give up
Recommendation switch
Choose Line 6 HX Stomp. Keep the compact Stomp and avoid duplicating those controls.
Choose Line 6 HX Stomp XL. Its physical controls solve a documented workflow limit, with expression still separate.
What matters in practice
The smaller processor can need more external controls, while the bigger processor does not provide more processing power.
