To draw a parallel from character encodings; all characters can be encoded in Unicode. There's the trivial fixed-length encoding (UTF-32) which is really, really easy to decode. Then there's UTF-1, which is a variable-length encoding that's not self-synchronizing and involves additions and subtractions to decode fully. There's plenty of room to argue about both, but it's not obvious that UTF-1 is better than UTF-32 or vice-versa. UTF-1 is more compact on common texts, UTF-32 is far simpler and faster to decode.

But there's also UTF-8, where the encoding is a little less efficient than UTF-1 (some codepoints are 3 bytes in UTF-8, but 2 bytes in UTF-1), but which has some nice properties for decoding (self-synchronizing, byte -> codepoint is simple bitfield extraction). UTF-8 often ends up being the optimal encoding for marked up text - the markup tags are always single byte characters, which makes up for the longer encodings used for some text.

I'm not a skilled enough hardware designer to know what a good variable length encoding would look like - I would guess, for example, that you want all instructions to be a multiple of a base word size (16 or 32 bits), and the first few bits of each word to tell you how to find instruction boundaries even if you've fetched in the middle of an instruction, but beyond that, I'm out of ideas.

For example, I'm not sure whether it's worth spending bits on "if you go forward N words, you hit the next instruction boundary"; yes, the decoder's life is easier if it can look at an arbitrary word and jump straight to the next instruction boundary, but is that worth paying for? I'm also not sure if you want self-synchronization or not - it feels right that a decoder can look at the first few bits of the instruction and know if it's in the middle of an instruction or not, but again I'm not sure that's worth paying bits for.

I do know that care is needed here - you've got Itanium as a fine example of an architecture with fixed length instructions that's still a pig, and Thumb2 as an example of an architecture with variable length instructions that's not too bad to decode.
