Yes, the baseline plastics will be less durable but they’re usually also less expensive. Most people will get a baseline or midgrade plastic for their putting putter (because they’re also gripper). Definitely get premium plastic for your drivers and midranges for the improved durability.
I know the GCP has its flaws, but I like mine a lot. Definitely get a backflush basket and some cafiza to clean it regularly. And then also look into the OPV 9 bar mod from Shades of Coffee if you want to tinker a bit. Sounds intimidating, but it’s just a replacement spring for the over pressure valve. I enjoy the resulting espresso more after I made the mod.
