Whatever suits your needs best of course.
I'll throw this out there....I thought in addition to my LCT I wanted a single stage to leave dedicated to universal decap die. Bought the classic cast - nothing fancy. And at times was convenient to have right there and leave the turret alone. But eventually gave it to a buddy getting started in reloading since it wasn't worth the bench space. It's literally a 5 second process to pop out a turret, pop in another that has decap die in an otherwise unused hole.
Even if you had the LCT and the index rod never moved once - wasn't even there - just the convenience of leaving a turret ring setup is really nice. For the most part, you set your dies up once and that is it. Extra rings are cheap - like <$10 cheap. I liked the simplification of once I had a set of dies doing everything exactly as I wanted, I could change calibers or not load that caliber again for months & months, yet it was ready to go in seconds next time. Changing projectiles had to readjust seating die & auto disk, but that was it pretty much.
Either way, I'd lean toward Lee since you already have the shell holders you need. They're cheap and maybe universal and the Lee shell holders you have work on any brand press - I have no idea - so not a huge investment, but you do already have all the Lee ones you need.....
The Classic Cast I had seemed nice. Single stage wasn't for me, but that wasn't the press's fault.
But I get the "I only want single stage" mindset. My uncle is that way. He gripes about how he dislikes having to load .223 in volume to feed an AR because it takes so long....but won't consider a turret to make it more efficient. His solution was to add a second single stage so he can go from one operation to the next, double handling everything...... but whatever you're comfortable with is what matters most I guess.... And the Classic Cast did feel "stronger" than the LCT. Just beefier and you don't have the turret ring moving up which looks odd at first. Never broke anything on the LCT and it did countless thousands of rounds for me. .308, .223, 300BLK, .45ACP, .40SW, .357SIG, 9mm, .380ACP, .38SPCL, .357MAG I think are everything I ever did on it.
I don't know how much press is needed for reforming brass so the LCT might not a good choice if you do lots of that. Converting 5.56 to 300BLK is all I've ever done along those lines - it held up to that just fine, but other types might be a lot more demanding.
