I'm sure it's very subjective. I'm sure if I really tried I could get my all eyelet boots off faster than the ones with speed hooks.
For me it seems faster with hooks. I also only use the first pair of hooks and then wrap the laces around the boot so I may be cheating. I could do that with the all eyelets but it looks weird to me. So I think its probably marginally faster, at best. And that is just my personal opinion. No actual time trials on my part;)
