Switched to straight razor a few years back...now I can never go back to anything else!

benefits:
no razors in landfills
no more razors to buy
better exfoliation...skin feels awesome after
it's like meditation
it's bad ass...strangely, girls often think it's hot to see me shave with a straight razor.

cons:
up front costs...yeah, they're not cheap, and there are required accessories (strop, strop paste, honing)
maintenance: you need to strop it every time you use it, and I get mine honed about once a year.
