Ruth Miskin and Jolly phonics is essentially the same method, they are just packaged differently.
Jolly phonics is ideal for the young child. The handbook has lots of games and Jolly Learing produces lots of lovely resources suitable for small children.
I think that Ruth Miskin materials are well written, her scheme is very through and business like. It suits older primary school more than pre schoolers. I like Ruth Miskin's book on how to teach spelling.

Not appropiate for a pre schooler though, but I have been using it with my six year old to teach him how to spell.
The Ruth Miskin decodable books are nice in that they show you how to test comprehension. Although my son prefered the Jelly and Bean books and the yellow and green jolly readers.
I used the Jolly phonics hand book and then the first decodable reading books I used were Jelly and bean. www.jellyandbean.co.uk
I felt that the red Jolly Readers were too difficult for inital readers. The yellow and green jolly readers are good though. Oxford Reading Tree Songbird books some of the best decodable readers, but are very expensive.
It is not so much a reading scheme, but understanding how the structure of the English language works. I picked and mixed from various schemes. I also made up some of my own resources.
