AMD used to be seen as the cheaper option that was the "budget option." However, AMD has amazingly caught up to Intel these days, producing CPUs that are definitely on-par with current Intel processors at competing prices. I would use a spec comparison site to see and if it's within your budget and you're fine with AMD, it's currently a very viable option. Personally I still use Intel but AMD has definitely made a great comeback.
I've been using Intel forever and I haven't really had any problems. I'd go with Intel right now. While AMD is growing, that's true, Intel is already an expert at being in the lead
