Yeah theres a lot of this nonsense flying around on the internet
'im a chiro, chiros are better than physio'
'im an osteopath, osteos are better than chiros'
give it a rest. We're all taking different approaches to treat our patients, just let your results speak for themselves. Its pointless to compare as besides anything else not all physios use the same modalities for each condition as everyones clinical judgement is different, same for STs.
I would say that regardless of your eventual intention to treat athletes, you will find it MUCH easier to get a job if you do physiotherapy, and the course is funded by the NHS so your get your tuition paid too. I did physio and came straight out and started working for a premiership football club at academy level, would i have got that job if i'd done sports therapy instead of physio? I honestly dont think so, theres not a single ST who works at our club their all chartered physiotherapists (although i dont have a very wide scope there, my club might be the exception not the rule). You also have the wider oppurtunity outside of sport if you decide its not for you (Neuro, respiratory, burns, amputees, c.o.e, blah blah blah) that you cant really do if you take ST. Obviously my opinion is pretty biased though, being a physio =P
