You haven’t mentioned the color of your switches. Most of mine are white but the kitchen has black switches with stainless steel wall plates. Two years ago the only brand I could find with interchangeable faceplates was Leviton.
The other places I’m doing Levitons (one done, one on the list) are more personal preference than anything. We have two rooms that each have two doors. Next to each door there is a 2-gang box with the two dimmers controlling lights via two 3-ways.
I wanted smart dimmers so the light level could be adjusted no matter which door you came thru. And they were not in a place where we would be talking to Alexa. The Leviton dimmers, both the main switch and the auxiliary, have a separate small rocker and a line of LEDs that control and show the light level.
Most of the smart dimmers look almost identical to on-off switches. Tap for on or off, tap and hold to adjust level. If you’re not doing it via a voice assistant or app, it’s hard to make small adjustments in the light level. This is much easier with Leviton’s separate dimming paddle.
As @JDRoberts said, the auxiliary that Leviton requires for 3-way dimming makes it fairly expensive. And it has very specific wiring requirements.
Along that line, Zooz ZEN27 are arguably the least expensive 3-way dimmers because they work with the dumb switch. I think the Inovellis now do that, too.
GE/Jasco use an auxiliary switch that’s inexpensive.
