I have a Brother NQ650 inovis which is slightly different that what you are looking for but having the ability to do the sideways stich is one of the best selling points to me. I would recommend you go spend some time 'in store' using the machines to decide which you would get the most use from. We can give you opinions, but you will be the user so you must take the time to familiarize yourself with the machines to make your decision.
I have no complaints about my Brother machines, and I have used three of them in the last 28 years and never found a reason for regret. I have also never had one of them in the shop for any reason. I do my own cleaning regularly, and I can only guess this is why they have never needed to go to the sewing machine doctor? IMHO
