I worked for several years with the immediately lower DW model, the 621K, and i am very happy with it; it does not weigh a ton, it has stable and easy locks for plunging / calculating depth etc, the service proved wonderful, and I have no complaints whatsoever.
As the DW is getting old, last year I decided to buy a stronger one BEFORE the DW dies in my hands; so I bought the Trend T11 (practically the T10 with some extra bits for table mounting) and I am sorry to say that one year later, I am still struggling to learn its habits; the depth lock yielded 3 times in my hands, unable to hold the strong springs; twice I had to throw away the template, and once the workpiece as well. The base of the DW621 is made of 2 parallel straight sides and two circular ones. The T11 has only one straight side, and all the switches are on that one side, so the machine rests on its circular side and not on its flat side. The hole in the middle of the base is huge, and it makes absolutely necessary the immediate construction of a subbase for any reasonable use. the weight of the machine requires some prep at the gym, but keep in mind thast the 625 may not be lighter. The point for the T10 is that Trend make all kinds of collets for their T10. The overall build, weight and awkward use make it a cumbersome thing to use, while the DW remains a "calligraphy" instrument for me, but also keep in mind i may be biased because I have been using it for much longer than the T11.
