In the last 6 months I had no post by suesa where I regretted my vote later :) add to that me proofreading most of them, so I know what I vote on.

I like to read posts from people I follow when I have time, not at exactly that moment when they post. That is asynchronous and in my opinion needed in a global environment. But for curation I need to react immediately, hence automatic voting.

I don't think that I have to comment on every post I read, mostly because I don't always have something meaningful to say. So I don't think that there is a one fits all solution here and for me autovotes complement my manual voting perfectly.

Edit: for a few days steemvoter was down and I still voted most my autovoters pretty fast but it sucked a lot. That time is better spend reading the posts ^^
