It's probably OK on an older toilet. But newer ones have a "Sani Gloss" finish in the bowl that keeps the bowl cleaner. I replaced all four toilets & that finish works very well.
We've replaced two out of three over the past 18 months. They had all been installed/replaced during a major remodel nearly 30 years old and were starting to run. DH was getting tired of fixing them and parts were increasingly hard to find. We'd have needed to change out the toilets eventually anyway, in order to sell a home in Los Angeles the toilets have to be modern water-saving models.
The new ones are higher (very easy on and off), have two flush options (solid and liquid), and are much thriftier with water.
@win231, I didn't know about the Sani Gloss finish, but have noticed how much easier it is to keep the new ones clean. DH will replace the third toilet this winter/spring.
An unexpected couple of giggles: During different visits, my two grandchildren ( 7 & 4) came to me with great consternation immediately after using the new toilets. They couldn't figure out how to flush them. I duly went into the bathroom with them and showed them the buttons on top of the tank. I explained that the big button was to flush poop and the smaller button was for pee. They had the same follow-up question: "What if I do both?"
