I've got two boys at St. Anthony’s and have been happy with the school. We think it strikes the right balance between academics and pastoral care. Our eldest is in year 6 and has just been through the 11+ gauntlet on the boarding track. He is sporty and academic and has received offers from Eton, Brighton College, and Harrow. We couldn't have hoped for anything more. Friends of his on the day school track are going to Westminster, Saint Paul's, and Highgate. As noted above, however, the school does not bill itself as “selective” so there are other boys for whom those are not good options. From what we've seen up close, the school really does put an effort into helping each boy find the place that's right for them. I know that can sound like a throw-away line, but having just been through the process, it is really important to find what is best for your individual child, not what will impress the neighbors.
In contrast, we were personally turned off by the “hothouse” vibe and reputation of the Hall. For us, subsequent years have borne that out. If you search, you can find comments on here by Hall parents describing the competitive and sharp-elbowed environment there as well as the types of boys produced by it. With all these schools, to the extent you can, try to understand how much their senior school results are down to the school themselves and how much are due to either tutoring or selection. Anecdotally, we saw a lot of Hall kids on my DS teams vanish from club sports during the first and second terms of year 6 because they were being put through a rigorous tutoring program. We have also heard stories of some elder siblings (ex-Hall) who are now struggling at top day schools they were tutored into. If I were a prospective parent, the recent scandal involving their head of ICT would raise a lot of red flags about the quality of safeguarding and employment screening. That is probably something you will want to look into. Not sure if it's connected to the departure of their headmaster.
We know one boy at Hereward House who is incredibly sporty and frustrated by the school provision in that regard.
Don’t know anything nor have I ever come across anyone from TR.
