Just get the biggest TV you can afford.
With the type & qty connection input/output that you need.
And the basic user friendly system that you are comfortable with.

The rest I let my android box supplement the extra that I need.

for me last time I choose sony kd55x7000e rm3k total incl. with 5yrs wrty as well as wall bracket & installation.
After you decided and bought 1, stop researching other tv brand/model, less you will never truly be peaceful.
