I'm level 41 with my Marauder and I am enjoying it like hell tbh, I admit that I've had a diffucult time leveling it, sometimes I had to use a medpac on almost every pack of mobs or saberward and cloak of pain, It was most problematic at 28-35 for me then I respecced Annihalation and always used Quinn at my back and I'm having no problems in questing, I have solo'd all my quests except for heroic ones without a problem and I notice that I do a fair bit of damage in PvP, I can at least make healers or other ranged panic when I charge them, the only problem would be that I'd like a bit more survivability, but I can do fine right now. It requires a bit of patience to become successful while playing a marauder and some skill and understanding of melee classes, if you've got that and like playing warrior classes then by all means, go ahead. Those who complain about the class are many people who are not used to playing warrior classes.
