Esker Japhy vs Salsa Timberjack
Both published charts held against each other, on the specs that decide what the bike carries.
The short answer
The Japhy is ahead on frame bag space and tire clearance. Nothing here goes the other way.
Assembled from the differences below rather than written over them, so it cannot drift from the table. Every figure is the manufacturer's; nobody here has ridden either bike.
Where they differ
3 of the 6 things we can compare come out differently. The rest are close enough not to decide anything.
Frame bag space
67 cm² more on the JaphyFront-triangle area at the largest size, computed from stack, reach and seat angle. It is what decides how much full-frame bag you can run, and a frame bag is the one place weight sits low and central.
Widest published tire
5mm more on the Japhy on 700c / 29inThe frame figure, not the fork's — forks are routinely cut for more rubber than the rear triangle, and compared only on a wheel size both frames publish. Loaded, tire width is also seat-pack clearance: a big tire and a sagging pack compete for the same space.
Chainstay
10mm longer on the JaphyThe gap between seat tube and rear axle, which a rack, panniers and your heels all share. Longer is more room for a load; shorter is a more compact bike. Which you want is a preference, not a winner.
Side by side
Including the rows where the two are level, because a spec that doesn't separate them is still a spec you might be checking.

Drawn to scale
Largest published size of each, built from the charts rather than illustrated. The front triangle is the part that decides frame bag fit.
