Most of us love our machines so are quick to recommend one like we have. But you need to find the one that fits you. Go online and compare features, find the features you want then go to the dealers, friends or quilt shows that have machines and try out the actual feel of each of them. No one can tell you which is best, you need to "drive" each one and determine which one is best for you.
I quilt with a Gammill Classic 14 foot table. Bought it new at West Plains, MO, 10 years ago. No bells nor whistles but I love this machine. I have never had a problem with it. Before I bought this machine I tried the A-1 and Nolting because there were dealers within driving distance of me. The A-1 and Nolting just didn't feel as easy for me to drive as the Gammill. I have never regretted my decision.
