Law insurance: yes/ no/ which one?

I consider getting a law insurance. but i read alot about them varying widely in quality and price. Does anyone have good experience? please list here!

what i found so far (all german)

i got highly recommended to require free choice of attorney, and what you read from this limited literature is that the contract conditions vary significantly, so you better compare them in detail. the kassensturz has a nice overview in it’s pdf table
they also write that there is the ever-lasting conflict of interest between the client who wants to go to court and the insurance that waives in case of suboptimal prospects for success
