Most of my purchased Android gear has been Samsung:
Samsung Galaxy S
Samsung Galaxy Tab 7.0
Samsung Galaxy Note
They seem to have the best hardware at present, although HTC have a good "One" range now. If I had no Samsung devices I would be considering the One S or One X, mainly because of the camera
As for Motorola, I am done with them. I bought the original Droid (Milestone) but Motorola have refused to unlock it for 'business' reasons. Thus it's stuck with Froyo. Goodbye Motorola
