Settle down there Tiger.
Subjectively unis are better on the wallet at the pace you (and others go through gear) on hear. That's all there is to it, nothing more nothing less. Though customs will have a much more consistent sound.
I agree with
@CrocodileDundee here:
Arguably the nature of universals actually make it harder to create a consistent sound (even when not factoring in unit variance). Unis are just going to have a bigger variance overall and not representative of how a custom might sound at all. Thats just the nature of it.
The A12t does sound different from the u12t, but I actually prefer it more myself.
