I've been trying out different spoke patterns recently (too much spare time on my hands
3x is without doubt the most solid, durable, and pretty easy to build, loads of guides on t'net.
Snowflake is almost as easy, never given me any problems either, even with off-road abuse, and does look a bit different.
Radial on the front could be cool, again if done properly I've found no down sides to this pattern.
3Leading 3 Trailing, bit of a bugger to do and by all accounts isn't particularly strong, ok for road use I guess
2 Leading 2 Trailing, you can't do this unless you have 32 hole rims, for 36 hole rims use the one above.
Crows Foot, like you say needs different length spokes, is different and pretty durable though.
1x and 2x, you may as well just go 3x surely??
Personally I'd go for 3x, safe, solid, reliable. If you want to change at a later date then with 3x it's easy enough to turn it into a snowflake pattern, just make sure there's plenty of spoke thread in the nipple and you'll be ok.
