While I would tentatively say “Yes” on the thrust, I sure have not regretted going bigger than necessary on mine.
Same with batteries. I have two Lithiums that are both at the high end of what they recommend for power. I have had to switch in a couple of high wind King Tide days.
As was said, and I do the same, I will lock my kicker in place at just above idle and steer with the bow mount.
One advantage using the bow mount is slowing a drift with it and having it hold the boat in a bow forward position. If you hit a good spot you can Spot lock to hold it there, then when it peters out release the spot lock and go right back to controlled drifting.
Once you get used to using one it would be hard to go back to not having it.
You can also program it to follow a pattern, and at the end, reverse the pattern back to where you started. It remains in the system if you save it so you can go back the next day and do it again.
My only complaint, if it really is one, is once you give it a command it may go full thrust to do it, which can be a bit abrupt.
