Have used many variations of several. The next thing I'd setup from scratch would probably be all IP based devices (i.e. no "hub").
The reason for this is the ability to choose and switch in/out devices that I actually want. Also like not being forced to use system compatible sensors/devices or being forced upgrade everything when changing systems. The only devices that I have been using for a decade+ are those that are IP or similarly stand alone. All the integrated stuff slowly drops off the wagon, just due to the hassle of keeping it up to date and integrated.
However, IP isn't really available for traditional security devices at this point, so for that pick a system and try it
.
Don't get me wrong, all integrated stuff is neat, but in every case costs a ton of time to keep it up to date with your daily life changes.
FWIW, In practical use, I thermostats mostly and external camera's occasionally (eg. to view the water frozen, boat on lift after storms, etc).
That being said, if $ caution to the wind go ahead with any packaged system and have it installed or DYI the whole system install.
