My regular line up includes:
Cube Alfa 73cm by American Tourister. Love it. Nice and light, 4 wheeled spinner. Has had a solid 2 years use, and no issues at all. Great value for money. Picked it up from bagworld for around $200. It is of course covered in marks from head to toe, but still functions perfectly.
Never have any problem seeing it, as its sky blue. I love gawdy colours.
Samsonite Firelite 75cm. Bought this as a treat to myself as the Cube Alfa was starting to look disgusting. $400 later, and quite frankly, I prefer the old Cube Alfa. Its fine, does the job, but nothing special. My only gripe about it is the side with the zipped fabric divider only has one zip on it - so always has to be zipped and unzipped from the one corner. I love the two zip option which gives me the option of where I want to open the compartment from (eg useful for just shoving those last minute purchases in while at the airport or when limited access in the boot of car full of other luggage)
Samsonite Blite fresh 55cm spinner. I do prefer hard sided suitcases for the protection factor, but until someone can invent a hardsided cabin case that allows me to easily access it while its standing up vertically, and pull things out without my knickers dropping out! I will stick with a soft case for carry on. Very happy with this one, is holding up well to a solid years use. Only issue is I tend to put my laptop either on top of the inner section, or in the zip section on the outside , to allow easy removal at the security line, however this tends to make it front heavy, and it is very prone to tip overs when I do this. And yes, once again the girly side of me loves the colour range this case comes in, electric blue for me.
Kenneth Cole Manhattan laptop bag - great for day trips, or for use in addition to the blite above. Lots of compartments for chargers, paperwork, business cards etc. Nice long shoulder straps means it can be comfortably worn over my shoulder when I need my hands free. Nice, slimline design, rather than the bulky, manly, doctor case type satchels. Only comes in black - yes I would buy it in bright blue/green etc if it existed.
(Im the same with my cars, why go black/white/silver, when you can go lime green/electric blue
