I knew from the beginning this was going to be a difficult topic to pin down. I’ve been hesitating on it for a month.
In a practical sense (@BluPenguin 
) I think we can limit the comparisons to specific components or entire esk8’s.
I mean something like R/C ESCs vs VESC 4.12 derivatives or the Hummie deck vs LY Evo. In both cases I think there purpose built product findings better for it purposes and is a better value.
You can also go the other way, my Beast Mode build vs the LaCroix Nazare. I built Beast Mode, a clear example of adaptation and I own a Lonestar, a clear example of purpose built. I’m very partial to my build, obviously, but I almost always grab the Lonestar when I’m headed out for a ride. I feel like that defines, at least IMHO, that the Lonestar is superior.
What other examples of this type of comparison can you guys site?
