t͡ʃ, t͡ɕ, ʈ͡ʂ all sound so close to my poor ear that I'd struggle to articulate the difference. They sound like exactly the same thing at slightly different speeds.

The latter two are distinguished in Mandarin Chinese, the difference between ‘q’ and ‘ch’ in Pinyin.

Note that that isn't the only difference between the Mandarin sounds. Pinyin "q" is also a laminal consonant, not an apical one.
