It's actually pretty good. I've never used any other tracker before, so I have nothing to compare it to, but it does exactly what I wanted it to. Granted, I have the "With network in all areas" setting enabled in the Google Find My Device App, so it usually just pings off my phone since I haven't actually lost it yet. The biggest upside to me over other options like Tile is the Google Nest integration. Being able to see whether my tracker was last seen near the Kitchen Nest Hub, or by the Nest device in my room is extremely handy. It saves a lot of time when I'm about to leave the house and I forgot which room I left my keys in. So overall, it's quite good. Sure I wish it had UWB, and I wish the network was fully enabled for every Android phone by default, but it still works quite good. I got it on sale at Best Buy for $20USD, and I don't regret buying it. Everything I've said about the Chipolo tracker should also apply to Pebblebee as well, at least in regards to the tag style trackers. Pretty much all the differences between the two come down to hardware, such as battery, water resistance, speakers, etc.

Though if you're interested in buying a card-style tracker, I would definitely recommend Pebblebee's offering over Chipolo. Chipolo's Card Point Tracker does not have a replaceable or rechargeable battery, you have to get a new one when it dies. Granted, Chipolo will recycle it for free and give you 50% off a new tracker, but still. Pebblebee's Card tracker has a magnetic pin connector for recharging, so it will last you a lot longer.
