Really all depends on what you want from the car. As a p plater, you are restricted in choice, yes, but if you know you want out of the car, that's your first step imo. If you want a quick car, there are things quicker than NA skylines for sure (s2k's, ep3rs, golf r32's). Some luxury creature comforts? Different cars again. However, if you want a skyline, you want a skyline.
'bad rep' you probably see, imo, is because with turbo versions available, they really aren't all that quick (and essentially all complaints you've listed comes down to that fact... --> "not worth it") etc etc. Haven't driven an NA 33 myself, but I don't think they'd be as shit as an overall as you may have read... but it's all relative. If your criteria for shit car is $x money for y 1/4mile time, etc.
End of the day though, it's your choice. If you're happy with your decision, all is good.
