Not every Bitcoin hard fork is worth claiming (this process is quite complex sometimes if forked coin doesn't have replay protection). Both Bitcoin Cash and Bitcoin Gold were interesting because they were different. Bitcoin Cash hard fork increased the block size limit in order to make transaction faster. Bitcoin Gold was supposed to make Bitcoin "decentralized again" and replaced ASIC mining with GPU mining like it used to be a few years ago. There are some small hard forks which don't get much attention. If you don't have a lot of BTC, it isn't worth to bother with smaller ones.
