I thought I would share my experience as I have been down this road too. The short answer is that both are excellent and you cannot make a bad decision.
Optically, I think the Meostars are a little better. They have better CA control and better resolution. The Torics are completely color neutral. The newer Meostars have a more neutral image than the older ones, but may still have a slight warm bias, IIRC. Optically speaking, my biggest issue is that the Torics image feels farther away for some reason. Twisting the eye cups down one notch helps, but then the eye relief is a little too short for my eyes. This was the main reason I bought a pair of Meostars. It might not be an issue for anyone else because I don't recall seeing this criticism anywhere else. It's not enough of a problem that I won't use them, just an area for improvement.
Both have good build quality. The meopta is legendary for it's tank like build, but that comes at the expense of more weight. My 8x toric has the smoothest focuser of any binocular I've ever used. It's buttery smooth and a joy to use. Admittedly, this does seem to vary from sample to sample in both brands, IME. They focus in different directions, if that's important to you. The Meostars focus clockwise toward infinity.
Here is where the Meostars start to separate themselves. The eye cups on the Meostars are removable for easier cleaning and more comfortable to my face. While both are perfectly serviceable, I can use the Meostars for much longer with out discomfort. I've noticed that this issue grows with objective size. I cannot recommend the 15x56 Torics for this reason alone. Someone with a wider IPD, might be ok with them, but I can only use them for a couple of minutes at time. The toric 15x eye cups are huge! All sizes of Meostar eye cups are comfortable for me. Tract eye cups are less comfortable in general, but become increasingly uncomfortable as objective size increases, at least for me.
Customer service is fantastic from both companies. A message sent from the tract website will elicit a response from one of the owners within a few minutes, even after hours. Meopta is equally impressive. They sent me some free lens covers when I asked where I could buy them, though they only respond during normal business hours.
At the end of the day, you will be happy with either. I give the edge to the meopta Meostars, but most of the differences I've noticed are relatively minor. There is nothing that can be seen with one that can't be seen with the other. I feel like the most significant differences are ergonomic and subjective. I prefer Meostars, but if you can't afford a meopta, or just want to save save some money, get a Toric and don't look back (except for 15x56). As others have noted, watch Tracts outlet section for a discount on demo models.
