Both are great. I have an F1 in my main machine. I have used both extensively and never seen a broken one (and I do see a fair few broken hard drives - more Maxtor and Seagates than anything else these days). Both drives perform very well and you'll be pleased with either purchase.
I'd go for the F1, but that's just personal preference.
