Island Table Or Dining Table Height Is Better?

[mrmrstan 2]

Would like to seek advice between the two..

We will be getting our ID to do up a customised long island table..this will double up as a dry-food preparation table (baking, making breakfast etc). And will serve as a gathering table when we invite family and friends to come over for meals

we are thinking if we should be..

1) keeping it at island table height

or

2) making it the usual dining table height

the thing about making it the island table height is that we only have the option of higher chairs/bar stools.. am thinking in the long run will it be comfy and suitable for the old and young

if it's the usual dining table height perhaps there's more options of chairs..would you think it's a more relaxing way to sit too?

any comments appreciated, thank you!
