Not in the context of TV criticism they're not. The things that annoy you about the adaptation diminish it in your eyes, so you can't gauge how compelling an experience it would be for the majority of people. I've never seen The Wire and only ever saw the pilot of Breaking Bad, so I can't comment, but I don't see why comparing GoT favourably to these two shows is an invalid, insulting or laughable opinion.
I think I have the objectivity necessary to consider how the TV show functions without letting fanboy irritations that things are different from what I'm familiar with get in the way. In fact, I would say familiarity with the source material is an advantage in that it makes me more conscious of the choices that the TV show is making, and the effect they're trying to create through these choices.
Being shocked by an unexpected development is nice, but it isn't that great a testament to the enduring quality of the work, and knowing what's going to happen doesn't mean you can't get invested in the experience. Psycho isn't a great movie because OMG PLOT TWIST, it's a great movie because Hitchcock is a master at building suspense. One of the problems I have with the show is that it relies too much on those SHOCKING MOMENTS (RW, Ned's execution), and in retrospect the rest of the episode feels like a way of marking time until we get to the next big shock.
Why do I think it's pretty far out there to compare Game of Thrones to the top TV shows? That's kind of hard to say without going too much into detail about the strengths of the shows I like better. One of Game of Thrones' problems is that it's a mostly faithful adaptation of a series of fantasy novels, so the show doesn't have the freedom to go its own path because it needs to stay in shouting distance of the plot of the novels. All of the (in my opinion) best television series use the format to great effect, while GOT is constantly trying to fit a square peg into a round hole. Those other shows are also better acted and better paced and don't routinely feature sex scenes ripped straight out of a soft-core porno and don't make me roll my eyes nearly as often and don't feature Peter Dinklage's atrocious accent.
