You will need to visit Brother dealers and try out their machines to see which model suits your need.
As for the bobbin thread coming to the top, there could be a few different reasons: wrong weight of machine embroidery bobbin thread, tension adjustment of the bobbin case is off, bobbin race and surrounding bobbin area needs cleaning, top tension to tight, top thread not feeding as it should, wrong type or too thin stabilizer.

That just sort of happens on any embroidery machine if your top tension is tight enough, (or the bottom tension is loose enough) to actually pull that bottom bobbin thread up to the top. Most times you don't get a whole new machine over it though, as it really could happen on just any machine.
I think first thing to do, is make sure you really got special thinner made for embroidery kind of bobbin fill in the bottom of it. Then sometimes it helps if you actually use the same kind and brand that others with your same machine use too, just because there are different weights and thickness, and even stretchy-ness of it, and that can make a difference just on whatever machine you happen to use.
Then in order to get less "pull" going on that is causing that top thread to pull the bottom bobbin fill to the top of the embroidery, you can try to just loosen your top thread tension a bit, by turning the top tension dial or setting to a slightly lower #, that might work good, and be less likely to pull that bottom thread to the top there.
After that, (and probably last choice and should only be done last if you have never done this before) you could actually if you wanted to and understand tensions, even tighten your bobbin case tension screw up a little to try to do about the same thing as doing the opposite on the top thread instead. But, know that little screw is very, very short, and can fall out pretty easy, and just get lost real easy, so if you choose to do that, I think you should at least do that, while holding your bobbin case over a bowl or such. Right is tighter and left is looser, and it does not take much of a turn to make a big difference at all.
If it only happens on some or one embroidery design, I would not do that though, as sometimes it can even be the properties of a particular embroidery design that can even sort of cause that to happen- I think not worth changing that screw (if you don't know how to do that) for just one particular embroidery design at all.
Also, if your top thread ever catches on anything or gets tight and restricted in anyway, that will just always pull up the bobbin thread to the top of the work too. Why it would get tight and restricted, I don't know, but maybe miss threaded, not feeding off a thread spool right or even thread getting caught in a razor like slit , thread end holder in the top embroidery thread spool , or just top thread getting hung up on anything.
