The big spiders I'd be fine with. You can see the thing for starters.
You also find that the bigger an animal is, the less aggressive it is, as it has less to prove in its environment.
Again, the Bird Eating Spider isn't massively venomous. Don't get me wrong, I wouldn't want to be bitten by it but given the option of.
Dinner plate sized spider I can see and hit with a spade that will give me a wasp sting type of bite.
or
Tiny spider you can't see that can hide under the toilet seat, in your shoe, in your trousers, etc - that has a bite that will either eat away at you flesh where it infects (like a Black Widow), or kill you in under an hour (trap door spiders).
I'm taking the massive one and a spade every single time!
