Depends on what you want to do with it and how much you're willing to spend. I suggest to save up and buy once/cry once.
There's generally 3 tiers based on spec, parts, and QC. The Colt M4 is par, some makers like Noveske go above that with CHF barrels and M249 double chrome lining (like S.A.W. barrels), and others cut corners and are thus sub-par.
Top tier:
Noveske
BCM
LMT
Colt
Saber Defense
Daniel Defense
Spikes Tactical
2nd tier:
Bushmaster
Stag
Smith & Wesson
Armalite
CMMG
3rd tier:
RRA
DPMS
Oly
Then there's the others like Vulcan, Hesse, and some others that you want to avoid like the plague.

It's cutting off the right side so here a link to the full version.

I've owned many from Noveske down to Oly. If the goal is simply plinking, any will do, but I'd still get the best you can afford. If this is going be for high volume shooting, carbine courses, or you plan to depend your life on it if zombies show up I'd go with top tier (or 2nd tier and perform the upgrades).
For a solid middle of the road cost effective rifle, I think Stag wins. Just stake the gas key.

I have one and also built one for a friend. Very good rifles. They also have cold hammer forged barrels and are milspec (aka on par with Colt). Haven't run mine super hard yet so we'll see if it can hang. I reckon it can.
