Agree with what many people have said so far.
Very hard to advise what the best wheel is for any one rider, but some general rules apply to all.
Using easily available parts to build a set of hoops makes any future repairs a lot easier.
Using thin gauge butted spokes are strong ( have used revs before) but a pain to build/true with as they wind up or twist and requires a lot more time to get right.
For the same weight I would use Cxrays or aerolites Any day with a bladed spoke holder, no wind up, easier to build with, no unwinding or re-truing after riding.
Brass nips are obviously stronger than alloy, but found alloy to be ok at high tensions if you lube them and use a 4 sided spoke wrench to avoid rounding them.
Carbon rims have been amazing to use, but have to get the hub perfectly in the centre before bringing the tension up, as you cannot easily correct out of round, as the carbon rim is so stiff it won't give like an alloy one.
If you get a high quality Hubset like dt Swiss, Chris king, hope, etc.. They will last a very long time, and can be rebuilt over the years with new rims. Just get a colour you love.
Built up the last set as 2x, not the previous 3x, based on some research on lateral stiffness, so far so good, they have tracked really well.
Some of the mass produced wheel sets these days are really good performance and weight (E.g. Xtr) hard to beat, but long term hard to get spares. So I guess if you can get them cheap, then great value, but probably not a long term option for lots of kms over many years.
I enjoy working on my own bikes, so having custom built wheels is the way to go for me, as long term I can repair them myself.
