I can see why some people tend to believe powering up is the best option. However, I've met a bunch of people on Steemit who doesn't really care about Steem Power at all, because they're looking for "fast, quick and easy" money. These people tend to focus on SBD instead of SP.
Personally, I usually go with the 50/50 option. The default one, as I truly believe I'll benefit from both currencies.
