These days (ARMv7 and above), Thumb-2 is preferred for everything but performance critical or system code. For example, GCC will by default generate Thumb2 for ARMv7 (Like your Tegra3), as the higher code density provided by the 16/32-bit ISA allows for better icache utilization.

Support for this state is signified by the "J" in the ARMv5TEJ architecture, and in ARM9EJ-S and ARM7EJ-S core names. Support for this state is required starting in ARMv6 (except for the ARMv7-M profile), though newer cores only include a trivial implementation …Bits: 32-bit, 64-bit
