I left out the most obvious advantage of the blinds in my last post.

Of course, the blinds get the HUGE advantage preflop of being last to act, even if they do have forced bets. If you have a hand like TT or JJ for example, under the gun, you're likely going to want to make a sizeable bet. Now if one person shoves all in and another (or 2 or 3) call, you're likely going to want to dump your hand here. In the blinds, you can see these people going all in, and just lose the much smaller amount of the blinds by folding here.

Or, to your advantage with a hand like TT or JJ in the blinds, this time you might just see 1-3 limpers in the pot. Shoving all in now seems like a decent decision (if its late in a tourney and the blinds are big), as you aren't very likely to get a call, and with the limpers, at worst its a coin flip if they call, and its possibly better (a limper could have A9s, an underpair, etc.). Whereas, in the same hand UTG, you could make a solid raise, get too many callers, and have overcards on the flop.

So there is a much bigger advantage for the blinds preflop over UTG. But there may be an advantage post flop as well. In any case, UTG certainly doesn't have enough of an advantage post flop over the blinds to outway the huge advantage the blinds have preflop. So yes, I'd definitely say overall that UTG is in a much worse position than the blinds.
