Generally in woodworking you get what you pay for. But there are exceptions.
This is my table saw,
This is my MFT set up,
In terms of accuracy of cross cutting I can't tell the difference between them, they're both as precise, at 45 and 90 degrees, as I'm able to measure. In terms of how clean the cuts are, again it's difficult to judge one better than the other. The table saw has a scribing saw facility, but the anti-spelch features on an MFT work so well that, with care, it can handle brittle veneered work equally well.
If it's so brilliant why doesn't everyone use one?
Well, there are limitations. It's probably at it's best with man made sheet goods, it's not great for ripping, in fact it's pretty poor in that respect. The thickness capacity is more restricted. Cross cut stops are less convenient. And the range of angles you can work with isn't as convenient outside a small number of pre-specified angles.
I used to work in the US and had the chance to see how woodworking was done differently there, I was struck that there was a definite sub set of hobbyist woodworkers who consciously decided to work primarily in sheet goods (ply, MDF, etc). They'd often have an MFT table and a track saw, along with a Domino and a biscuit jointer, as their main tools; and they were very productive! Kitchens, built in units, fitted furniture, you name it. These guys were churning out stuff at a rate of knots to a pretty high professional level.
I wondered why their counterparts don't really exist in the UK? I think the answer is because sheet goods raw materials are expensive. They're not much cheaper in the US, but somehow that was a bullet that American hobbyists were prepared to bite. Where as spending several hundreds (or even thousands) for multiple sheets of Birch Play or veneered MDF is too much of an up front commitment for UK hobbyists.
