Thanks to my chronic indecisiveness, I've now ordered and tried the sports, Milanese, leather loop and classic buckle straps. (The link is on its way!) Surprisingly, the winner (so far) is . . . the sports. In my view, it's easily the most comfortable, though it does pull at my arm hair when I'm putting it on. The black looks really terrific with the watch. (I originally had the white, which was a big disappointment. I haven't tried the coloured ones.) The Milanese looked good in the box, but I didn't like the asymmetry (loops on one side, but not the other) and I personally didn't find it that comfortable. I thought it was too long: my wrists are 178mm and the 42mm strap went almost all the way round, which I didn't like. I sent it back. The leather loop looked better than I was expecting (I got the black) but it wasn't cushiony soft as I thought it might be and the loop part is quite awkward: it sticks out and caused skin-indentation on my wrists when I lay my arm on the table, which I do a lot at work. I got the medium and, again, I felt it was too long. I found it quite hard to put on. I find the sports extremely easy to put on. (I sent the leather loop back.) The classic buckle was dull to look at and I didn't like the fact that the leather doesn't go straight into the watch like it does on the leather loop. It wasn't a great fit for me: I was between two holes. I found it surprisingly hard to put on and take off: it kept catching on itself. I sent it back. Which leaves the link, which I'm expecting delivery of next week. Not sure how I'll cope with an all-metal strap, and whether it will cause arm-hair trauma. If I like it, I'll keep it, but I'm more than happy to just have the sports. It's funny how Apple seems to get away with its prices. I was looking at straps for another watch a couple of weeks ago. The most expensive they had in the shop was a crocodile leather strap for £89. The Apple leather straps are £129.
