the Arkels aren't super tough, so you just have to use common sense with packing and sharp edged objects, but they are super light, completely water proof and as you say, have a smaller profile.
Only downside is not easy on, easy off, but for cc stuff, generally you'll have the bike with you in a hotel room, so even easier to just leave them on.
Snow--how about a photo of your bike?
ultimately, for rear panniers, there are tons of good ones out there, I personally put an emphasis on waterproofness, and there are many models out there by various companies that will be fine for your use.
I can't remember snow if you have toured before? I guess not if you are looking for panniers. If there is a chance that you will use panniers for commuting etc in the future, it makes sense to get some well made, easy on easy off panniers that will get used by you in the future.
