Which one would you choose?

The Python templates are *much* faster than the GPM templates. I would pick one of them. However, that might affect how you can maintain them.

Edit: ahh, with python the view is always cleared.

The templates I provided don't take into consideration the fix I made (in source but not released). They both will clear a virtual library. The search version shows only the requested book (the result of the search).

Given my fix, I would use a modified version of the first template that generates show-book links. It is functionally equivalent to the original GPM template, including not clearing searches, but much faster.

python:
def evaluate(book, context):
	cache = context.db.new_api
	ids = book.get('#mytextmult', [])
	answer = []
	for id_ in ids:
		if cache.has_id(int(id_)):
			answer.append(f'<a href="calibre://show-book/_/{id_}">{id_}</a>')
		else:
			answer.append(f"Book id {id_} doesn't exist")
	return ', '.join(answer)
