Which brands offer the most durable toilet push buttons?

I visited a bathroom fixture shop to check durable toilet push buttons two days ago. I wanted something that lasts long and works smoothly every day without getting stuck. I also wanted something strong because my old button became loose after few months. But when I checked different brands I felt confused. Some push buttons looked very stylish but seller said they are more for design than durability. Some looked simple but felt stronger when pressed. Some prices were very high but I was not sure if quality is really much better. One seller keep saying every brand is same but I was not believing him. I could not trust them. I could not decide confidently.

Then I visited another shop in the same area. Some push buttons from Kohler and TOTO looked very solid and smooth in movement. Some Grohe models also felt premium and heavy. Some local brands were cheaper but button action did not feel very stable. I remembered my cousin installed a cheap push button before and after some months it started sticking and flushing became weak. That made me more careful again. One worker was explaining internal mechanism but I was getting more confuse because many buttons looked same outside but worked differently inside. That made me hesitate even more.

To check more options I searched online while scrolling many marketplaces including alibaba. I found many toilet push buttons from different suppliers and brands. Some reviews say Kohler, TOTO and Grohe are known for durability and long life. Some budget brands work fine but may need earlier replacement. Some listings also include complete flush kits for better compatibility and smoother operation. This made me excited but also confused again. Now I am thinking should I invest in premium push button for long term durability or choose cheaper one and replace it later if needed what would you do in my place?
