Jard, or maybe timney. Some have good luck tinkering with springs/making adjustments, with the factory trigger, etc.

Going to try and adjust the existing now. If I don't like it, I'll look into aftermarket.
A long-time "standard" for CZ factory trigger improvement is a YoDave kit. Check here for the 457 kit.
I had one for my 455. Definite improvement, and the 457 trigger is reportedly much better to start with.
Be aware: YoDave is a Canadian company. While the kit doesn't cost much, postage from CA involves some sort of border-crossing fee which is ridiculous - at least it was several years ago - ~$10 plus postage. The company has no control over it.
Maybe things have changed. Maybe there are stateside vendors who stock the kits. Do a bit of research... there were alternatives to YoDave springs when I had my 455 (pre-pandemic) as well.
Good luck.

I tried a YoDave spring and the McMaster Carr springs. The YoDave was a little heavier than the McMaster at the lightest setting, but the trigger is adjustable so unless you was super light, both work well. The YoDave comes with a nice nylon block to assist driving out the trigger pin, but not absolutely necessary.

That's what I ended up with. I bought a Jard but the Timney won the contest... Mine is a CZ 457 MDT Chassis. I really like the Timney.

First the SCAR triggers are like a unicorn to find. The Timney is 10oz +. The Jard is my favorite. I ordered it with the 3-6 oz and it came from the factory at 4 oz. I ordered the 10-12 spring just in case that was too light. This is my range rifle and after I got used to it, I have to say the Jard eats the Timneys lunch. I have a Mr Fly in my 455 that breaks at 6 oz. I love both these triggers. Incidentally, if you have a 455 the Fly is for sale for 100 bucks on CZ's website. It works without any mods in the B serial on up. The A's need mods but can work also.
At the time that I got my trigger, there were 2 main contenders. Jard and Timney, so I got both. In terms of pretravel/creep, over travel and break, the Timney was much better. The Jard could go lighter in terms of pull weight, but the Timney was better for me. I run it at about 12 oz and it's very clean.
The spring kit will get you about 80% of the way there and would be fine for field use, but if shooting small groups is what you want, the timney was it for me.

I think maybe your Jard needed some adjusting. What pull weight did you get? I got the 3-6oz and it came from the factory at 4. I dont have any creep or pretravel. There are a lot of adjustments that can be made but I didnt touch mine. As soon as my finger touches the trigger, there is resistance but not a defined wall. It breaks right away with minimal pressure. I ordered the 8-12 spring with mine because I was unsure if I would like that light of a weight. If I like anything about the Timney its the felt wall. Mine breaks at 8oz. I prefer the Jard overall.
Maybe I didnt articulate it well enough, but the point I was trying to make is that there is far more to a trigger than how light the break weight is. I am fully aware of the adjustablility of both triggers. It was my experience that the Timney is the better trigger. It's just plain more refined with a glass like break.
I misunderstood and we are actually saying the same thing other than for me I like the Jard better but I am using mine in a bench scenario. For a PRS scenario I also prefer the Timney which is what my second 457 is set up for.
