Don't get a seat which covers multiple stages if you can help it. If you have to combine stages, and sometimes it makes sense, then combine two but not three. What tends to happen with combination seats is they do one role well and the other(s) badly or they do them all in a mediocre way. Your car seat is a safety item and it's helpful if it is optimised in design for 1 job or 2 very similar jobs.
If you have a budget of £300, want good reputation for safety both RF and FF, and like the idea of the swivel I would go for one of:
Cybex Sirona Gi i-Size
Maxi Cosi Mica Eco i-Size
Britax Dualfix M Plus or Dualfix 2 Z-Line
They are all similar in terms of the quality of the brand and the premium of the seat as the one you've chosen, but they don't combine a high back booster mode in with the rear and forward facing, which is a lot of roles to expect a seat to cover and is likely to result in compromises both in safety and also in practicality.
Stick the £50-80 difference in a savings account if you want, and get a separate high back booster when she outgrows this seat. It's SO nice when you get to the age where you can ditch the massive, heavy, bulky isofix base type seats and swap to something much more streamlined - and grown up feeling for DC as well, and you're doing yourself out of this pleasure by opting for an all-modes-in-one model. Also the toddler stage is very hard on your seat - it will be truly manky by the time she is 4/5 and I don't think that these combination seats are as comfortable for older children as a good quality HBB. (105cm is about 4.5 years for an average sized girl - the higher weight limit on the Cybex and Britax is a slight advantage).
Joie Spin is cheaper and is fine, but IMO it is not as nice a seat as these three. E.g. my 3yo is very upset at RF in the Joie spin now because he says there is not enough room. He can forward face in it, and mostly does anyway as it helps with occasional car sickness but I did like having the option to switch him round sometimes. Also, ideally I would not pick Joie for FF. I would like to move DS3 to his older brother's Britax seat but we have had some other budget constraints come up so he is staying in the Joie for now.
Would also recommend going to a John Lewis/Mamas and Papas showroom and checking out the seats in person there :) The Britax Z-Line is amazon exclusive but it's basically the same as their other Dualfix models.
