I have a 1433v. I have only touched a 1528 at a dealer last year. I do know shift lever is in different spot, the side as opposed to the center deck. Like CDsdad mentioned, you can see the brochures for both series on MF's web site. If you are looking at buying one of the two, then I suggest looking at them and comparing the differences and decide which you like best. I bought mine slightly used (140 hours), so was able to save a lot of money over buying new.
