The best Stream Deck for streaming, and whether you need one at all

A control deck does not make your stream look better, sound better, or hold a higher tier. It is the only part in a desk build that buys nothing except your attention back, which is worth stating plainly before the prices, because the alternative to buying one is free and works.

The Mini is the expensive one

That is the counterintuitive result in the table and it holds up in use. Six keys sounds like plenty until you lay out what a running stream actually needs: a scene, a second scene, a BRB, a mute, a clip button, a light toggle. That is six, and you have no room left for the thing you think of in week three. The MK.2 costs $28 more and gives you nine spare keys at half the price each.

Elgato Stream Deck MK.2

The pick at $108 tracked. Fifteen keys is the size where you stop rationing them.

Elgato Stream Deck Mini

Only when desk space is the binding constraint. On price alone it loses to the MK.2 per key.

What the dials are actually for

The Stream Deck + swaps seven keys for four rotary dials, which is a good trade only if you have something continuous to adjust: a music bed you ride against your voice, a mic level you nudge, a light you dim. A key is binary and a dial is not, so the question is whether anything in your stream needs a value rather than a state. For most solo streamers the answer is no, and $92 more for four dials and seven fewer keys is the wrong direction.

The free version, honestly

OBS binds every one of these functions to a keyboard shortcut at no cost. The real difference is not capability, it is that a labelled physical key is findable by feel when you are already talking and something has gone wrong, and a keyboard shortcut is a thing you have to remember correctly under pressure. Elgato also sells a phone app that puts the same buttons on a touchscreen, which solves the memory problem and not the finding-it-by-feel one.
