I can see it going full steam ahead, myself, for a few reasons:
1) Do both, for additional safety.
2) PrEP has changed formulations, and may change again. This implies that the previous formulations were not completely optimal.
3) From what I understand, PrEP can be expensive, although your insurance may cover it. You can also get it overseas for much less but many are not comfortable with that.
4) It's a lifetime expense, even with insurance and a lifetime of having to take a drug versus one or more shots.
5) Not having to undergo kidney function tests on the regular might be nice.
