Smaller is closer to the schematic and PCB, no warnings More work finding space for a resistor as well as future claims and causes of action with respect to end users, business partners and the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that.
