I think the environment and everyday maintenance needs consideration.

Most decking seems to me to have not enough gap for detritus to fall
between the boards, and if it is caught between the boards it's a
bitch to clean out and/or off the joists.

We have a lot of overheard and nearby trees. When I replace this
decking with composite nobody should/will be permitted to wear heels
on it (hasn't happened in 10 years anyway), I might so as wide as
1/4".

Don't worry about high heels. My toes get caught when I walk on our
dock. If a small child is
walking barefoot, gaps too wide might break a bone.
