I put 17" on my 6th gen Accord. There are two ways you can go here, then flavor to taste. Either you want light weight for performance or that bling bling baby look of chrome.
I suggest you buy what you can afford to, understanding that one day you will rub up against a curb and forever scar your lovely rims. If you are patient you will go for forged three piece polished in a 17x7.5 or 18x7.5 (my favorites).
If ride is an issue, the bigger the rim the smaller the sidewall of the tire, the better the grip, the harder the ride. Also, I find that the more you upsize the more touchy the handling gets.
My choice is a 17x7.5 forged three piece polished...but I don't have that! I have 17x7 lightweight MSRs (19lb each). A compromise. So, when I hit that curb I didn't really worry too much because they were relatively cheap!

good luck!
