Opinion: The medium between Abaranger and ToQger
This may be me personally but I very much see Gekiranger as this mid link between abaranger and toQger, which I didn't previously link to each other despite being my two favourite sentai. Gekiranger picks up a lot of the elements from Abaranger, starting with a main trio of rangers, however it does a lot to make our redeemable villains seem actually redeemable. It's another soft red who is willing to welcome even the worst but we see put through circumstances that they aren't prepared for. There's a lot that can be analysed into the influence of abaranger on this and this on ToQger, though there's probably other seasons in between that will also have had influences.
While of the three this is my least favourite, know that that's only because the other two are the absolute top of my list, this is far far from my least favourite and I thoroughly enjoyed it.
In conclusion, hell yea watch Gekiranger. But also know that it's got all the good fart jokes.
