OSPF Virtual Link confusion.

Consider a scenario

R1---R2---R3--vlan3

Link R1--R2 is in OSPF area 12
link R2 --R3 is in OSPF area 23
VLAN3 on R3 is in area 0
Loopback int on R1 R2 and R3 are in area 0.

Now to connect dis contiguous area 0 i can have 2 possible solutions.

SOL1:
VL from R1 to R2 and VL form R2 to R3

SOL2:
VL form R1 to R3 and VL from R2 to R3.

I have seen in various WBs that they follow SOL1.
I have tested both solutions work. however thats the advantage of using
one over other? will I be peanilised for the solution I choose?

Thanks!
