Most WASRs are decent rifles. They are a little rough around the edges and won't score as highly for fit and finish or, to a degree, accuracy as the more expensive AKs. But AKs are like sex--even when they are bad, they are still pretty good.
As far as I know, most of the earlier issues with canted sight blocks and really bad trigger slap have been resolved by them training their monkies better and installing TAPCO G2 trigger groups. Expect good reliability and 4 to 6 MOA. You may have to do some light machining to the mag well and/or magazines and such, but the WASR will do what most people do with AKs.
The WASR is probably best served as either a beater rifle or as a basic platform for customization. If you are looking for a rifle to throw in the trunk or behind the truck seat or just want something to take out to the gravel pit to bump fire and turn money into noise, the WASR will do it. Or if you are looking to get to know the AK inside and out by tinkering with it, replacing parts, ect, the WASR works really well. I had a basic general knowledge of the AK before I got my WASR. Since I've had it, I've replaces front and rear sights, trigger groups handgards, stocks, and pistol grips. I now feel like I have a mch better standing knowledge of the AK, what I like on it and what I don't, and what its capabilities and weaknesses are. It has been expensive, though. So if the OP wants a top quality rifle that will represent what the design is capable at the very up limits of it (your?) capability, an Arsenal or Saiga conversion will be slightly more accurate and will show better fit finish and quality control. If the OP wants to learn a new platform and isn't afraid of taking the scenic route, the WASR is a perfectly acceptable way to get there.
