AKo (button) facing raise from EP and 4bet by CO - 25NL

[Sup3rM4N]

PokerStars No-Limit Hold'em, $0.25 BB (6 handed)
MP ($35.10)
CO ($31.20)
Hero ($27.85)
SB ($40.65)
BB ($25)
UTG ($28.25)

Preflop: Hero is Button with K, A.
UTG raises to $1, 1 fold, CO raises to $4
Hero: ???

I'm still new on the table so no good read on either UTG or CO, cept they haven't done anything crazy. I can't see calling as an option here since UTG might reraise, so either fold or raise/push? Do I need a good reason/read to raise/push this or would I be too tight if I folded?

I always play AK like AA in this spot. Push all the money in the middle.

why would you shove AA here meeloche?

Since it's 25 nl, I'm very likely to get called by at least 1 plus since I'm doing it with AK, QQ and KK I don't see a point in not grouping AA with those. I definitely see the benefit in smooth calling though although I do think it shows just as much strength as shoving if not more. Right or wrong i feel like I always want to to make moves with a range instead of a hand since i feel like that way it makes me harder to play against. If I'm smooth calling AA here that means I would be smooth calling AK, QQ, KK which I don't really want to do since I will be c/f a fair amount of flops with missed AK's and QQ and sometimes KK. I want to ensure that I'm always putting my range in when I am the largest favorite and in this case that happens to be pre flop.
I am definitely interested in hearing responses to this thinking though.

NL25 I'm folding, I'm still not seeing enough 3-betting to warrant a call/push. You're flipping at best usually...
