As far as how accurate these are:
Morpher is based on the original '93 toy. While the molds for that were used for buckles on the show, the stickering is different.
In MMPR it said "Power" on the top half and "Rangers" on the bottom with some lightning coming from the outer letters.
The Green Ranger's Morpher should be gold and his shield is too large.
All of the helmets are inaccurate in terms of shape and detail placement but that said, neither Bandai nor Hasbro have nailed them either and to a casual viewer, they may not be able to tell the difference. An example would be, the bottom of Red's Visor should be pointed. The worst likeness seems to be Black Ranger's but if you're happy it has tusks and a visor I'm sure you won't mind. I can provide picture comparisons if anybody needs.
I've got over 15 versions of the MMPR ranging from Original 8 inch, 3.75 inch, automorphs, Legacy, 2010, new legacy, hasbro, micro machines, movie, etc... and these regardless of their faults might be my favourites. I've been longing for clothed versions all my life.
I only wish the articulation was better. Its hard to bring the arms up any higher than 90degrees on the males. I don't know if this is due to an undersuit, poor body used or the latex like chest diamonds placed on the spandex. The "Calling for Zords" pic below I've done is merely camera trickery as I can't get that arm any higher.
