You can do articleship as per your preferences. Aspirants usually choose a renowned firm for doing articleship as they provide proper knowledge, skills and experience. Keep the following points in point while deciding to join a firm for articleship.
Do not select based on stipend provided. Choose a firm near to your place, sort out everything priorly before joining such as stipend, working hours, leaves etc., Choosing a Big 4 is not compulsory. Do what you feel convenient for yourself. Learn while working and try not to feel it as a burden.
Hope this helps.
Good luck!
