cf with steel liners can generally be thinner and lighter. (keyword: generally. there can always be exceptions)
Feel and appearance is so subjective. CF can have different textures, some glassy smooth, some with more grip. TI is generally not too grippy unless it has a milled design in it or something, but it is not slippery feeling like stainless steel.
Ti has a natural "warmth" to it that I love, and the frame locks often "feel" sturdier and more quality than a liner lock, even if they are not.
cf doesn't do much for me. I don't dislike it, but I'd only go after a cf model if it had a steel or blade design I couldn't get in something else.
my current favorite is Ti framelock with a g10 scale on the one side. Nice mixture of grip and quality feel. Ti also wears in nicely in my opinion. After a bunch of pocket time the edges get worn shiny, the little dings and scratches from using it hard look great IMO. Like a light patina for your handle imo.
