What is the best whole home system that you can control with one or two apps?
Depends on your budget and your needs. 
If you can spend $40,000 Plus an annual maintenance fee, then probably control4.
If you just want a simple reliable system for lights and locks under $300/room and you have an iPad, Apple’s HomeKit is a reasonable candidate.
Aside from those, there are a lot of other options, but this particular forum is for people who are using the Samsung SmartThings ™ Home automation platform, so all of the questions and answers are assumed to be in that context.
If you are looking for a general discussion forum on home automation, try the Reddit subforum. It’s brand agnostic.
Sorry for posting on the wrong forum. Thank you for pointing me in the right direction.
