K5's or K10o

I prefer K10 offsuited even though K5s has more possibility of making flushes, but it will depend on the range you are playing in, if you are playing a lot of hands it may be that you open both is a personal matter

The 5 in the K5s is the tough pill. K 10 off give you better possibilities if straight does not hit

Both are only marginal at best, but I feel like my preference depends on my opponents. KTo is better for hitting something with the board (also susceptible to being dominated by something like AK, but naturally K5 is crushed by more potential hands), whereas I like 3-betting with K5s more due to slight equity to the flush outs and the blockers (5 blocks the lower straights like 5-4-3-2-A and the King of course blocks against hands like AK).

I guess my answer is: "it depends"
