Itch or GoG?

Hi,

I own Caves of Qud on Steam — bought it many years ago — but, for various reasons, do not want to be bothered with Steam anymore and just want to get the game in standalone form.

I have never used Itch or GoG. Is one better than the other? Is one more likely to disappear than the other? Or are they pretty much equal.

I'd appreciate any views.

EDIT: Oh yeah, while I'm here:I can't deal with small text for long periods of time. Are there text size options?

Thanks.
