RK myself. I am not a fan of the batwing's look. I have a RK and love it. Although, I'd probably love the Electraglide if I had it. Tough choice, but I don't think you'll regret either one of them.
Go with the standard, then you can make changes as you find out what you need. My 2000flht looked like a Street Glide before they were even made, think the MOCO saw it in my garage lol.
I think it all depends on what YOU want in a bike. I ride an RKC and am not likely to change but if I could afford three harleys (have to make sure and count the wife's bike too) I would have a street glide in teh shop as well. You can't go too far wrong with any of the touring bikes.
