I use a 3pt splitter, and it works great for me. The selling point was simple. I own the tractor, diesel engines are made to run, and mine has low fuel consumption, and I really liked the fact that I didn't have to worry about another gas engine, especially with the terrible things that result from Ethanol in gas. I also like to be able to fel my tree, chunk it, and then back up to it, split it, and its ready to be trailered and stacked. My splitter is a Ram Splitter PTO driven splitter that has a hydraulic pump, and a reservoir. It is very fast, only a 16 ton, and I have not met a log that I cannot split, including 30in oak logs. The other nice thing is that I can lower the 3pt, and load the log on. Speeco, and TSC sell a model that stand upright, and they work great, but they use your tractor hydraulics. I bought my splitter used on Craigslist, and I paid about what an entry level gas splitter would cost, but it was worth every penny, and it has the remotes on it. I am not sure that I have seen one that requires a separate set of remotes? I do like the gas operated splitters, and they both have their advantages, but I guess that I also felt that I bought my tractor to use with implements like this to make life easier, and it has not let me down. It also only takes up a very small area when I store it. I heat solely with wood, so the expense was very worth it for me, and it will pay for it self in one season, since I have split all of the wood that I need to heat for an entire ice cold New Hampshire winter, but if you are not heating with wood, or if you only need a cord or two, I would recommend either renting one, or getting an electric splitter. We used an electric splitter for several years, and I split about 4 cords a year with it, without an issue. You can rent a comercial grade splitter for about $80 a day at Home Depot. This is my splitter, and the company is:
