I wouldn't trust the opinions of YouTubers such as LockPickingLawyer. I don't think he fairly reviews locks as he never actually talks about the usability of the product and when he tests them his goal is to break it quickly as that gets him lots of views and he can make money from the adverts. A video titled 'Bike Lock destroyed in super-fast time' is going to get a lot more views than 'bike lock reviewed'. You have no idea how much testing he does before he hits record. There is no evidence he even owns a bike.
But you do have to realise that no bike lock is unbreakable. They are deterrents and a good bike lock will hold off thieves for longer but if they want your bike bad enough and are undisturbed then they are taking your bike. Whatever bike lock you buy, no matter how secure it is, also get some kind of bike insurance. Especially if you live in a city.
There are professional independent testing bodys such as ART and Sold Secure who test bike locks based on information from police and they use realistic tools and methods. This is the best way to judge how good a bike lock is and then you can find one that fits your price range. As I said, no bike lock is unbreakable but I'm sure there is one out there that best fits your needs.
Here is a good blog that mentions what to look for when buying a bike lock -
