Nobody can answer this question for you, people's preferences vary extremely widely, ranging from
"weight reduction FTW, who gives a rat's *** about cooled seats and ambient lighting"
"love the moonroof that lets some sunshine in"
"mansmission all day every day, real men row their gears, those auto guys are pussies"
all the way to
"even the 2SS doesn't have enough creature comforts"
"reverse mohawk [roof line] FTW, who the *** wants it cut up"
"the auto shifts way faster and the stick is impractical in traffic"
etc., etc.
Since you have a 1LE, test drive at least a manual and an automatic SS, then definitely a magical 6th gen 1LE. You will know what you really want after these test drives.
The A8 hate is strong here, but it's actually a great transmission, GM messed up with the torque converter and the factory tune. If it turns out you fancy the auto trans and want total peace of mind, get a 2019+ with the lower torque spec A10, though.
Just my 2 cents', as usual.
