The sorts of problems you have with higher power in the modern era tend to
be in RF pickup on the cable/internet boxes like ATT Uverse, etc. The old
stuff like phones & TV are not primary issues. The digital modes tend to be
more resistant to interference but the issue is more binary - meaning up to
a point, the RF from your shack is not an issue, and then a few dB more and
the box shows some issue. Meaning it's entirly possible that you may be
able to run high power and have no neighbor grumbling at all. Or you may
bump the power up by some fractional dB and hit a limit which pushes the
guys box over to a fault. Hard to know.
The good news is that if you have some bucks you can buy a box of type 31
ferrites and in almost every case there is some sufficient application of
the ferrites to the suffering box that will keep it happy even with your
full power transmission. The caveat here is that the closer the neighbor is
to your antennas, the more ferrites you will need.

Better antennas should always come before more power or a new radio with
more knobs.

I have been thinking a lot about buying some form of amp for my shack to do
400-600 watts on RTTY. Then looking out my shack window I am reminded that
I have a lot of really close neighbors and I do not want to put them at risk
with even more RF exposure. I also have a really small lot.
I am real lucky that the powers that be in this mobile home park I reside in
even lets me have radio, of any kind.
So 100 watts and better antennas are my options.
I just hope that I make it physically to the next sunspot peak. I did really
well with 100 watts during the last one.
QRP operators have a motto that I have lived by for years. "Power is no
substitute for skill."

If you're out to win a contest in the high power category, or to get
rare ones on the first or second call, go for the max. But here 400
watts or less has gotten 344 DXCC entities on RTTY, 5 watts has 268
and
1 watt 146 countries. Pecking order is propagation, then antenna and
power.
