How do these boat manufacturers compare?

I'm thinking about buying a used boat. I'm looking at these manufacturers. Are there any on here that I should avoid? Which are regarded as the more high quality lines?
In no order:
Renken
Chaparral
Four Wins
Crownline
Chris Craft
Wellcraft

Information that may be relevant to your answers:
I'm looking at either a runabout, or possibly a cuddy cabin. primarily it would be used for skiing/tubing, cruising, and some light fishing. the biggest i'd be looking at would be 24', but probably more likely 18-21'. I'm leaning towards a stern drive.
Thanks in advance!
The boat will also be used in fresh water only.

You stated you were buying a used boat, therefore high quality lines doesn't matter as much as how the boat was stored, used and abused.

for 10 year old 19' cuddies

A bayliner (considered low end) plywood core chop sprayed fiberglass sells for $10k to $20k brand new. If stored indoors washed and dried after every outing, and maintenance done to the motor. Low hours on the engine due to an adult couple only taking it out a few weekend during the summer on the freshwater lake by their house.

compares with:

a four winns (considered mid range) foam core woven glass layup costing $30K to $40k new. left outside with boat cover on, spent more time on the water due to family outing and pulling the kids on the tubes.

compares with a

cobalt (considered high end) solid injection molded fiberglass costing $80-90K new. Left outside in sun and rain, ran with anything from low grade gas to stolen camp fuel. Hauled by coast to coast by group of early twenties wake boarder trying to impress the ladies. Beached in the surf, carpet molded from beer and pizza stains. engine still has original oil from the manufacture even though it turned to crude about 1000 hours ago.
