Order of preferability for parse mode

[Loli]

So I wanted to know what is the most preferable way to parse? Given the possibility of using LR, CSS, JSON or REGEX which one is the best to use. Reliability- and speed-wise.

4 ways to parse a value, it will depend of the source response, most easy is LR

[Ruri]

• LR: Fastest option, but not very reliable and very hard on multiple lines
• CSS: Very reliable and easy (can be copied directly from chrome's inspector) but heavy on performances. Only usable on HTML or XML responses
• JSON: Fast, only usable on JSON responses
• REGEX: Can be really slow but it can achieve things that the other methods cannot even dream of (requires a lot of knowledge)

Thank you for the thorough explanation.
