Is it actually an improvement for Splinter to start out as Hamato Yoshi?

Mirage, 4Kids, original movies, first PD movie:

• It turns animals into humanoids, that's all it ever does.

Fred Wolf, Archie:

• Turns things into hybrids
• Seemingly works the same as in Mirage when no humans are present
• Fuses man to trash
• Turns man into goop
• Fuses animals of the same species together
• Fuses micro organisms to ice
• Turns rocks into rock soldiers
• Probably other things I can't remember

IDW

• In it's most raw form, it's a regeneration formula. If it does anything but regenerate lost tissue, restore youth or increase muscle mass, it has been altered. If any chemicals that alter the substance are used on their own the subject will die quickly.
• One variant does turn animals into humanoids (but somehow also caused a colony of flatworms to share a hivemind). A brain altering formula is required to ensure the subject don't become an idiot.
• Another variant creates creates hybrids and depends on what DNA has been added to it. The humanoids variant seeming turns into this when inside the blood of a mutant. Effects can seemingly be reversed with a cyybernetic pump.
• One variant seems to fuse things together but it's never been intentionally used and was seemingly in testing stages.
• If not kept sealed for long enough, any variant will yield worse results.

Nick

• In general it creates hybrids, in general.
• In it's natural state it's literally milk and regulates the ecosystem in Dimension X.
• Utroms are seemingly immune to the effects.
• It turns men into pizza when used as a pizza topping.
• It can cause existing mutants to mutate even further.
• It can fuse three different lifeforms together.
• It can create animal-plant hybrids.
• Can allegedly be used to create restorative medicine (though it seemingly didn't work).
• It can cause massive brain growth.
• It can give you psychic powers without any visible deformities.
• It can give mushrooms powerful fear toxins.
• It can fuse men to trash.
• It can cause body parts to come loose and mutate into their beings.
• It can cause rats to become giant monsters with plenty of deformities but without signs of hybridisation or a humanoid appearence.
• It can cause humans to become more Utrom-like, despite the Utroms being immune.
• It can turn cats into ice cream.
• It can turn men into goop.
• It made Shredder part metal.
• It gave squirrels the ability to reproduce within host bodies.
• It turned a car itself into a monster that could possess people.
• It gave wasps mind control powers and made them giant without any other deformities.
• It takes a long time to make a cure unless you add random nonsense to it so you can instead do it instantly.

Second PD movie:

• It... finds some ancestral DNA and turns you into something related to it, regardless of wheter that thing would logicially be part of the evolutionary line or not.

Rise

• It generally creates hybrids, usually based on what the individual ate or wore.
• Some arbitrary additional effects may happen, there's no logical reason Ghost Bear gets phasing powers but he does.
• Draxum thinks of Yokai and mutants as interchangeable, so it's not always clear what we see are mutants and what are Yokai.

That's basically it. Generally speaking, Mirage has the simplest rules, IDW has the most complex and Nick has the least amount of rules (pretty much none).
