I have all 4 of the jif saws mention...Bosch 572, Carvex, Mafell P1CC and the Trion. They are all capable saws and I them all for different reasons. The Mafell is hands down the best jigsaw I have ever used. It is the most accurate of them all and no fuss when swapping blades. I can make furniture grade joinery cuts with it and this is one I would replace if it broke or was stolen. It is jigsaw nirvana. It comes with a parallel fence as part of the package. The angle base is a separate purchase, but it is nice and allows scribing cuts. It also stops and an accurate angle guide. You position the shoe back so you can cut right to the edge of a perpendicular surface and side their are no blade guides, you can insert the blade in both directions to cut pushing the saw forward or pulling it back. The DC works amazingly well and it has 5 orbital settings.
I like the Bosch 572 for rougher work. It is powerful and cuts will. With thicker blades like the Carvex or Trion labeled blades or any Bosch blade labeled with a "DP" work well. Thinner blades and I get some deflection in thicker material. The edge guide allows you use this with either Mafell or Festool rails. It has a light and dust collection a metal plate that fits over the plastic shoe for rough work.
The Trion and Carvex use the exact same blade guidance so one is not better than the other in my opinion. The Carvex is lighter and has the lights and interchangeable bases, but the tilt base does not allow scribing cuts as easily. The Carvex has the best all around circle cutter of group and honestly that is why I have this saw. Some of the other bases are handy to adapt the saw to the work.
The Trion is a solid and proven saw. I like the blade guides even though they are finicky at times to adjust. But one dialed in you can get great cuts. If you do not need a light and want a strong jigsaw the Trion is a good value. It also has a rail guide that you can adjust for slop for accurate rail guided cuts. It also has a paral I parallel fence for ripping.
I actually use the guide rail all the time for cutting with all my jigsaws and recommend it when you need a straight and accurate cut.
So I would recommend the Mafell as the best, at a price (but worth every penny in my opinion). Second would be one of the Festool units, because you can dial them in for accurate cuts. I would probably pick the Carvex over the Trion by a small because of the circle cutter, but if that was not needed the Trion would be a great choice. The Bosch is a great saw too, but better for cuts that do not need to be perfect...so rough cutting, breaking down material, cutting travertine, drywall, metal, conduit and a host of other rougher tasks that a jigsaw is great to use. So if I could have two, the Mafell and Bosch would be my choices and I would forego the Festool units.
