No. It's only more suitable for orbital. In system travel times are measured in days at 1G. Half the year, it's faster to jump to Mars than get there at 1G.
That's an interesting point... perhaps for built-up star systems there are corporate insystem jump-ships, just jump-1 engines and room for a dozen passengers and light cargo?
No, more likely they'd have a few 4 or 5G shuttles as it's a lot less expensive on fuel.
