Is it worth one S-unit to you? That is the real question.

about your specific situation, if you're already at 50
watts, 100 is probably not worth the trade-offs.

Try 1/2 of an S-Unit.

No S-meter involved. A 3 dB increase in signal can make the difference
between unreadable readable.

While most people seem to agree that there is a
standard, almost no receiver is calibrated to the
'standard'. The low

I've asked this question before, but will ask it again just to see if
there are any new twists that I'm unaware of:
Our UHF repeater is currently equipped with a 50 watt PA. We have an
opportunity to install a 100 watt PA at moderate cost. Our site is
excellent and we are already using good

I would halve the power, tell the users that you have doubled the power
and watch the glowing reports of greatly improved performance roll in. :-)
That was the results I got 15 years ago when I tried the experiment.

Actually, it is 1/2 an S unit (6 dB = 1 s unit, if you believe
that sort of thing!)
My experience with an additional 3 dB on the transmit side on UHF is
that you *might* fill in a few holes
That's evil!

This was asked a while back, and the results were made into a web page...
http://www.repeater-builder.com/antenna/3db.html
What would be interesting is to add a few sound files to the above article
showing what a jump from, oh, maybe 6 to 9db quieting, 9 to 12db, and
12 to 15db actually sounds
Pretty close to the mark , maybe add a gain antenna and enjoy the results .

Nope. Not likely.
What would you do?
Buy a better antenna with the money or spend it on any upgrade that
would prove to require at least one less trip to the repeater
3 dB is definitely noticeable on my RXs.

Standards, you gotta love 'em. Everyone should have one. ;-)
