Hmm, I've been using a combination of the two for a while now. I use autovote on a few authors for two reasons: I feel they are under appreciated, or they have shown me a lot of support through many thoughtful comments and I want to return some of the love. Most of these auto votes are around 20% strength, so I have plenty left for manual curation.

I don't always have time to go through my feed and there are some people I feel deserve my support even when I don't have time. Whenever I do have time though, I go through my feed to find good posts to upvote. After that, I check out the rest of Steemit to find good posts elsewhere.

I like doing it like this, because it means I'm never at 100% VP, which would feel like a waste. I'd rather support a few people automatically so my VP gets put to good use.

I don't think this would change if they do implement these changes. I still want to have VP left to upvote random posts I enjoy.
