2SC2922/2SA1216: 2SC3264/2SA1295, they're also the same LAPT type, like 2SC2922/2SA1216.
Or, use parallel 2SC3519A/2SA1386A to get spec equal with the original.
TIP41/42: MJE15030/MJE15031, MJE15032/MJE15033.
However, show me the schematic then i can suggest better.

"Best possible" is dependent upon the particular application - voltages, gain, bandwidth etc. It's too simplistic to assume there is some universal "best possible" unless you are just choosing basics qualities like between cheap Ebay fakes and genuine parts.
As Walkalone states, 2SC2922/A1216 are LAPTs. There are newer versions also from Sanken but these unique MT200 style transistors, if genuine and chosen correctly within recommended ratings, are among the very best output transistors for linearity, power handling and Ft.
TIP41/42 are general purpose, low frequency power transistors. Sometimes they are used for so-so drivers in low voltage amplifiers. For medium-high power applications, MJE1503X family transistors are very good, but there are better drivers for premium low-medium power applications, starting with low voltage BD139/40, going up to KSC2690A/A1220A, 2SD669A/B649A, 2SC4793/A1837. Note that the last two pairs are obsolete but good clones are now available from Profusion (UK). Unisonic (Taiwan) are the manufacturers.
2SA733/C945 are low voltage GP small signal transistors. BC560B,C/550B,C will outdo these in most audio applications, as will 2SA1015/C1815 (if available). There are many small, low noise audio transistors that are generally higher performance but as before, the "best" will depend on the ratings and exact application.
By using Google or the search button at the forum header, you can find these equivalents and threads answering these equivalents questions many times already because we all have problems buying obsolete or rare, genuine parts. Sooner or later, we realise this is going to get even harder as thru-hole parts disappear and the only trustworthy supplies are SMD. The point is, the questions are answered many times already - search them first.
