[Timo]

As far as I'm aware, the differences between the TIs (Polar, TI and TI kb) and the Snow seem to mainly relate to polyphony (the number of notes you can play until it starts dropping out), multi-timbrality (the number of simultaneous patches you can play at once, like bass, chord, and lead sounds all together), the number of physical audio output jacks, the number of presets available, and the UI.

DSP chips: Snow is single-core (1 chip), the TIs are dual-core (2 chips)...

... Therefore polyphony of the Snow is approx half that of the TI. The figure quoted is >50 voices for the Snow, and >80 voices for the TIs, but how that equates to real-world values given varying complexities of patches requiring more/less power is anyone's guess. I guess it's quite variable.

Multi-timbrality: Snow has up to 4 part-multi, the TIs have up to 16 parts. (Not that you'd ever get to use that many even on the TI, due to polyphony etc.)

Hardware audio outputs: Snow has 2 x 192KHz/24bit balanced (+4dB) analog outputs on 1/4" TRS, whereas the TI has 6 of them.

Both the Snow and TI have 6 (3 x stereo) additional streams of audio via USB though, but these are limited to 16-bit/44.1KHz usage (for both TI and Snow equally).

Presets: Snow has 512 RAM and 512 ROM singles and 64 x 4-part multis, whereas the TI has 512 RAM and 2048 ROM singles and 16 x 16-part multis. (..At least I think).

The user-interface differences between the Snow and TI are obvious. Less knobs and buttons and smaller footprint, but Access claim they've made it as easy as they can do to navigate.

Otherwise, the actual sound mangling engine between the Snow and the TIs are identical.

So it just comes down to specifications, sizes, and your working habits. They both sound the same, just the TIs have a greater quantity.
