Simple answer. You need them both. You will just have to live without one of the tools until you can purchase the other. Personally I love everything festool but I got by for fifteen years without it. Don't skimp on either purchase. A full size table saw has too many uses. You will be disappointed with a bench top model.
I agree. I have both. I've had my 52" Unisaw for years and 5 years ago I got the TS75. After I got the TS75 I've been looking to get rid of the Unisaw. After all, with a 52" fence, an Excalibur sliding table, it's like a small aircraft carrier in the middle of my shop. It takes up a good chunk of real estate. And anything to the right of the 30" mark on the fence just has junk piled on top of the table. (In fact any horizontal surface in my shop collects junk, including my MFT). Now that I have the TS75 I never wield full sheets of plywood on my Unisaw. I "rough" them down to size with The TS75 in the garage then take them into the shop for further refinement on the Unisaw, where I can make quick setup for repetitive cuts. It would make sense that I could replace the Unisaw with an MFT3 or better yet, 2 MFT3's ganged together for long rip cuts, but then again, the same large footprint.
I have an MFT3. I love it. I use it for routing stopped dados and crosscutting work pieces. But to have it set up as a dedicated crosscut/rip cut jig......I just can't see it. When crosscutting, you have to carefully set it up square each time you use it. I use Qwas dogs. It's time consuming. And then when you have it all setup, you have to remove the saw, flip up the guide rail, change work pieces, repeat.....more time. Nothing beats the speed and ease of going over to the table saw, sliding over the fence or attaching the fence on the sliding table for crosscuts. Flip down a lever or turn a knob. Boom, done. I never have to double check either for squareness.....ever. And I prefer to cut through dados on the table saw with a stacking set. It's quicker.
If I had to do it over, I wouldn't get such a large table saw.
I'd consider the Sawstop contractor's saw or the larger one with a 1.5 hp motor, the one that looks like a cabinet saw. No more than 32" fence. Or if I had my way, a small Hammer would be ideal!
So going back to what cgraham recommended, you need both.
