Only two good heists in GTA V are Vangelico job and last one, because we're doing them for cash and ourselves. No higher authorities or reason.
And I would say they are almost on the same level as TLC. Reason why I don't like Vangelico as much is the tacky scripted getaway, when one hit destroys every cop car. Try to pull this out in normal gameplay. UD one is cool, especially with obvious approach, but the cop resistance is a bit too easy to overcome. In TLC you felt really trapped, when in The Big One, you're are the badass killing poor cops.
Paleto Score, Blitz Play and The FIB heists are rather weak in my opinion. Not only we're doing them for FIB, but they're also quite poorly executed. Paleto is nothing more than shootout with cops, mercenaries and tacky escape via train. Blitz Play is another shootout with cops (I like the way they grounded the truck - look at Robbie Williams "Road to Mandalay." And the FIB heist is just corridor shooter with elements of survival.
And the Merrywheater heist is so good, I totally forgot about it.
Summing this up, while TLC was probably on the level of Vangelico and The Big One it's stands out because it was just one heist in the IV (and first in GTA on such level of intensivity) and also just one of many missions in GTA IV, which is unfortunately not the case in GTA V.
