"You remain the coolest person I met" suggests that you are referring to a specific occasion on which you met a few people, of whom that person was the coolest. "...I have ever met" would sound better.
"I have ever met" implies that she is the coolest person you have ever met until now. You haven't met someone that cool in the past. "You ever met" implies a past action and might not be a good fit for your case and may not even sound correct to some people. For a past thing, I would say something like:
She was the coolest person I'd ever met.
Further to what Reg says, saying "You remain the coolest person I met" is nonsensical. How could the roll-call of people met on / in that - if not specific occasion, period ending with that specific occasion - have altered since? The set of candidates for 'coolest person met' has obviously been expanded in the intervening 3 years, so "I have ever met" is needed to include the period following the last encounter.
Simple answer that no one actually touched here is this:
One is in American English, while the other is British.
"I lost my phone" - American "I've lost my phone" - British
