Not sure what you're planning to buy. The Cherokees don't glide well
but one thing I like about them in a high density airport is just
that: you can arrive well above the commercial glide slope and do the
crowbar descent and avoid mixing with wake turbulence. But it's a
matter of what fits your flying style. At uncontrolled airports, you
want to enter the pattern low to increase the chances that unannounced
high wing traffic will be above you.
