PETG has become the second "entry level" filament besides PLA because it's almost as easy to print with (just hotter) and also doesn't require an enclosure. Not as stiff as PLA and has a little flex, so perfect for prints that don't have to be 100% rigid. For example I printed a smartphone holder for my bike out of PETG with 4 "arms" that grip the corners, and it has just enough flex so I can get the phone in and out. Temperature resistance is only a bit higher than PLA.
TPU/TPE are flexibles and available in all grades of flex, the softer ones can be tough to print on bowden machines.
The "kings" of temperature resistance and toughness are ABS, ASA, PC (blend) and PA ("nylon"), but they pretty much require an enclosure and good ventilation (fumes...) and have to be printed very hot, so an all-metal hotend is highly recommended.
