Controller Players - Evade Build - Thunderspike vs CDR

Hello my fellow Controller Users. It's Xbox in my case but PS or PC should be similar.

In Evade builds we hold Thunderspike at the beginning when we don't have enough CDR or the Unique Sepazontec.

All the build guides and YouTube Videos lean into the idea that you want to get rid of holding that button more than anything else. This may be true for m&k, but holding a button (for me LT) doesn't feel annoying at all.

Am I missing something? Is there anything good in getting rid of holding the basic attack? Getting Evade CDR up is a waste of tempering slots if it doesn't improve anything else.
