Hahaha! If you had to install W10 within the next couple of weeks - would you guys wait for RS4 RTM or would you settle for a more 'mature' RS3? I can't say I m really impressed with the new features from RS3 -> RS4 and I presume that there ll be plenty of holes in a newly released RS4 (but that applies to any newborn OS...). Then there's the added benefit of +2yrs of support (in favour of RS4). It's a dilemma
Building a custom RS4 image once the first RS4 CU is released then doing a full upgrade over the top RS3 with it. I will be using MSMG Toolkit to modify RS4 more or less the same way I have RS3 modified. I did this for RS2 -> RS3, it went off without a hitch. As far as a fresh install goes, I would not go RS4 until the first CU is released, just in case there is something major that needs fixing.
I would suggest do dual boot of RS3 and RS4 and slowly shift to RS 4 if everything is fine in it. Later on you can simply delete the RS3 folder and directory and its entry from the BCD record file. In this way you get a clean install as well which always give you about 5 seconds faster boot speed to windows.
