Interesting contest post, these are some great tokens that you have highlighted.

ATM I have only invested in proofofbrain, leo and hive although I do have a small but growing collection of many other tokens.

I tend to invest, power up or stake those tokens of the tribes that I use most, but in my experience it always helps to helps diversify as many tokens or coins as possible, you just never know when some of them will hit the big leagues.
