The Clipper

The Ibn Ezra (Koheles 5) criticizes the Piyutim of the Kalir.*

He has four main complaints against them. 

1) Most of them are Chidos (riddles) & Mosholim (parables) 

2) Instead of Loshon Hakodesh he mixes in Loshon Hatalmud

3) He invents words & uses improper Dikduk (poetic license)

4) They are based on Medroshos & Agodos instead of Pshat

The Teshuvas Maharashdam (O..Ch 35) claims, 

The Sephardic Paytonim  have a simpler and easier

language. Everybody can understand the Piyut, whereas the

Ashkenazi Paytonim use difficult words and even the

Shatz (Chazzan) doesn't understand what he is saying.

He recommends Ashkenazim to switch to Nusach Sefard,

which is a superior Nusach.  He claims "Al Titosh Toras

Imecha is only applicable when there is a small Issur involved

 and not for changing a Nusach Hatefilah.

The Chasam Sofer (Hagohos O.Ch.68) writes that "the Mahrashdam

wasn't aware of the Magen Avraham (68) who writes. you are

not allowed to change the Nusach Hatefilah because

there are 12 gates in heaven, one for each Shevet. Each one 

has his own Minhag. The Yerushalmi says, they are all equal

you should not change from the Minhag of your fathers."

Had the Maharshdam been aware of this M.A., he wouldn't

have written what he wrote".

Piyut of the Kalir starts with
