i tend to like most works by Sarasate.Thal
I know I keep recommending the same composers, but you should take a listen to Milhaud's second sonata for violin and piano, op. 40 (1917). This is a totally neglected masterpiece.Other suggestions would be:Georges Auric - Sonata in G for violin and pianoGeorge Enescu - he wrote three violin sonatas.

Beethoven, "Kreutzer" Sonata
The early Sonata in D minor and the three Paganini Caprice arrangements are rather weak, though. I would go with the earlier pieces.
Are you saying that they're weak in general or weak in comparison to his later works like Mythes? I think his early works are really good, especially compared to other works in the Polish repertoire.
Speaking of Polish repertoire, the pianist/violinist Grażyna Bacewicz composed quite a bit of violin sonatas (and other works for the medium). I quite like the fourth one.
Greatest violin sonata ever written, bar none. My spine chills just thinking about it.
