Confused about the different sources

Hi, i am new to this PS and have some qns in mind.
Given the source below.. are they of the same code base or different and able to support which version.

If different. care to explain which code base they are from and programming lang?

TCWNN
LOTF SOURCE
PowerSource

If i am to update them, which is more updated. Thanks

They Are Same Sources lol

And They r All a bit diffrent

They're all the same just get the original LOTF source and add everything yourself.

LOFT SOURCE = Oldest one, I prefer this one if you want to learn Coding,
TCWNN = LOFT Based, They just added some things,
PowerSource = Almost same as LOFT, They only got a external Database or something, ( I thought ).

I would not use any of them but the original cause the ones were people added stuff is mostly wrong or done in a way that makes it harder for future things.
Now co future (original not the co future release) is one were there a big change and that is were it would be more piratical to answer this. For all the ones you mention are all lotf
