A newer subdivision like Forest Grove generally means lower immediate maintenance and modern building codes, trading against smaller, more uniform lots and less mature tree cover than an older, established neighbourhood offers. Buyers choosing between a newer suburb and an older neighbourhood are really weighing move-in-ready condition against character and lot size, and both can carry very different price points block to block.
Amenities matter as much as the housing stock itself: proximity to schools, retail and a bus route can separate two otherwise similar new-build neighbourhoods more than the houses themselves do. That is a fair comparison to make between Forest Grove and any nearby newer subdivision, without needing to rank them on a single scale.
The comparison that actually predicts your sale price is recently sold comparables in the specific neighbourhood, not a general reputation one way or the other. Get your hand-reviewed valuation from Joel Dyck.
