There's no true answer because each model has its own pros and cons. Generally from what I've seen here's what to avoid. 1: 2017 initial imports. The first T81's especially the side folders had a massive QC issue with bent front trunnions which would commonly be referred to as having bent barrels. The barrels themselves were straight but in the assembly process the trunnion would possibly not be put in correctly resulting in a barrel that would be canted to the left or the right. The rifle could still be shot accurately when using the iron sights as the would still line up correctly however, this issue would make optic mounting almost impossible due to the deviation as even 1 mm to the left or right would significantly throw your shot off at 100 yds/m. Unfortunately this issue was overlooked in the initial import as turns out bent trunnions are fairly standard and considered in spec by the PLA. There is no fix to this issue unless you are capable of machining a new trunnion and fitting it in correctly. Thankfully this issue has since been addressed and mostly resolved 2: T81M under folders. They are a neat rifle, a nice variety change to the Canadian market, a great looking rifle and a nice throwback to some of norincos first EM series prototypes for the American market. The issue lies in its stock however. If comblock underfolders are known for anything it would be 2 things; stock creak and not being the most comfortable to use. Comblock underfolders can and most likely will develop stock creak and play with usage and time which can be annoying. The other issue is with the length of the stock itself. Unlike AK underfolders, the T81 underfolder has to be longer to accomodate for the mag which sits further away from the trigger than on an AK, though not an issue for some, this can result in a stock that has a rather large LOP. Aditionally, having an underfolder does further restrict you from optic mounting optics which are already limited on the T81 as is. The stock unfortunatley gets in the way of dovetail mounts and that leaves you with only a few options; leave the stock permanently open and fix a dovetail to the reciever, 2 get a rear sight mounted rail and mount an optic to it (can be hard to find and limits you to small collamitor sights), 3 find one of those lowpro adapters that mount to the hammer and trigger pin whithout obstructing the stock (these can also be difficult to find and also limit you in what sights you can run). The underfolder is a cool gun but, IMO unless you plan on running it stock, id say its worth saving and extra 100 or 200 and finding a fixed stock variant to run. As to what I would reccomend? If you want good quality and on a budget run an LMG, ive owned one before and they are great and fairly accurate. If you have the extra money and want something shorter or lighter with a fixed stock, try an 81M if you can find one cheap or a 2018 SE fixed stock, if you want a dragunov clone and are fine with limited mods, run an SR. If you have the money, want a light, compact gun thats built well and has a folding stock, run a 2018 SE folder.
