Well, prolly about 800 of my posts are touting the qualities of the Graphtec.
We have the CE5000-60, and we haven't looked back.
I was in the same position you were in when we were looking, but I trusted my Fiance, and we went with the Graphtec. It'll do come amazing cutting!
This is a thread I posted just after getting our plotter:
Why We Love Our New Graphtec CE5000-60 Plotter
I wanted to test this cutter's limits, so I did this as the very first thing I cut. mark told me it would never work, and he was MORE than pleasantly surprised he was wrong!
I'll happily send that file to a GX-24 owner to do a direct comparrison.

I'm curious how the Roland would handle this file!
That Roland owner needs to have a camera that will do macro pics, tho.
