It is an interesting discussion, I can SO understand wanting to home-ed!
My oldest DS was a fragile little thing at 6, did poorly at school in every way (socially, academically, emotionally), made no progress for 2 years, and had an awful teacher in year 3 who had no sympathy for his SEN (despite him being dyslexic, and also on social and emotional IEPs).
I cried about it, and lay in bed twisting and turning, worrying about him.
In the end, I chose to send him to a different school, for the last 3 years of primary, where luckily he thrived, caught up, and ended up with no IEPs, not even dyslexic anymore (how is that possible?!) and with lots of like minded friends (the "geeky" bunch, he'll never be a football kid).
Now at secondary, I am still slightly distrustful of the state education system, and think a lot could be improved.
I do 30 minutes English with him after school (he still cannot spell well, though he is "middle set", so I guess lots of kids his age cannot spell?) and I am currently watching "the World at War" documentary with him in the evenings (as his knowledge of 20th century history is non-existent) or the news (current affairs) , or sometimes nothing (playing on i-pad).
I also le him do technology clubs and fencing, slightly off-beat activities which he prefers to school.
What I a saying is, he is partly HE'd I guess, to "fill in the gaps". And I understand totally people who say the state system is not up to scratch for their kids.
I cannot imagine how I would teach him secondary maths and science though, so I could never HE properly. Also, he is now definitely getting a lot more out of school than at primary.
OP, no decision is for life, you can always change your mind again.
