+45 18x9? That's not bad. I mean, you'd wish it was higher but +45 is pretty good for that much width. I like the spoke pattern and solid color too.
You'll have more options with the +48 ones (enkei) so I guess they're handling wise a slightly better choice. You could easily do 245/35/18 on the enkei's but might be stuck with 235/35/18 on the 18x9's. 235/35/18 is an awful size with very few and very overpriced tires. Though, I don't know the 08+ fenders that well. You might be fine at 245/35/18 on the 18x9 +45.
If you're looking for something more conservative, you can out 225/40/18 tires on either of those wheels painlessly provided you go 18x8 (The 18x9 is too wide for a 225 wide tire). 225/40/18 is like half the price of 235/35/18.
Sorry, I'm rambling. Both companies make cheap but good quality products. Both 18x8 will work for you. 18x9 +45 pushes the envelope some (not an absurd amount) which has it's advantages if you know what you're doing.
