the first question you have to answer is do you want an electric cart, or a gas cart. They each have their specific advantages and disadvantages. If you are happy with the disadvantages of gas cart, and enjoy the advantages, then lithium is unlikely to be a game changer for you. You'll still have to charge and eventually replace a lithium battery.
If you want an electric cart because you know for sure you don't want a gas cart, then it makes sense to evaluate lithium vs. lead-acid.

I bought my first cart 3 years ago and knew I wanted the range of a gas cart, and did not want to deal with charging and filling LA batteries, or replacing them every few years. I bought a Yamaha Quiet-tech...I love it.
The opportunity came to buy a used Club Car electric from a friend who wanted to go to a lithium Evolution. I knew the cart had been well taken care of, but needed new batteries. I considered a lithium "upgrade", but decided to go with one more set of LAs because of limited availability of lithium, and wasn't thrilled with what I was reading about what was available. I may very well go with lithium next time around, if I decide to keep the cart. Hopefully in 3 or 4 years they will have made even more progress in price and performance and understanding of the technology in golf cart applications.

The electric cart will be a "second cart" for us, for when we have company. It won't be my go to cart for a long commute to a distant golf course, with 18 holes of golf in the middle. It will get light use, when the Mrs. and I want to be able to hear each other comfortably, maybe to the square for some music, or dinner, or pickleball together. I wouldn't personally go with electric as my primary cart unless I had lithium. But that's just me. The cart I bought from my friend served him well for many many years as his primary cart.
