I don't know if I can answer your question directly, but you seem to be on a path I walked, so I will tell you how I upgraded and why, and how it works. Walk a mile in my shoes, so to speak...
I started with a RCBS Jr press when I was 14. I am 60 now. I used that single stage for everything, including loading 1500 40SW and 1000 223 one winter. (I could do rt arm handstands when done!)
I use three different powder measures. All are Redding and all are specific to the load range I use (10X, 30BR and LR50) I do not have an electric trickler. I use stick and ball powders. All throw very well, and I throw a tad low and trickle up, unless it is ball and frankly, the smaller Redding measures are darned accurate.
I've always been pleased with this set up. However, I started loading in bulk and yet I wanted control over variables, so I bought a T7. It is as strong, accurate and works just as well as a single stage solid press. I see no issues at all, even with larger magnum cases.
What I love about it is I can set up two cartridges on it, plus I can set up a Redding Intant Indicator next to the seat die. I use Comp seat dies. I seat long, then click the turret over to the Instant indicator, run it up and measure, then wind the difference into the comp seat die, click back and full seat the bullet. This makes up for differences in the bullets.
I often load different cartridges in a sitting...sizing and prepping one, loading and seating others. The T7 has changed how I do everything. I love it and I would not sell it or give it away. I now use my Jr press for universal decapping only. I have a Dillon 550 that I use for plinking and bulk ammo, but when it comes to stuff that matters...T7.
