I used the KYB Excel-G struts on the 98 and 01 GT sedans with decent results. They are a "quick-strut" solution which means they come pre-assembled with new springs and are a snap to install. They are relatively inexpensive and will give you good service life, especially if the car will be a DD for the kid.
On the 02 GTP coupe I have now, I was looking for better handling, so I opted for Vogtland springs and AGX struts. I also added GMPP sway bars, new LCAs with Moog bushings, and tubular trailing and lateral arms in the rear. Finished it off with some 245's on 18x8 rims, now she handles flat as a pancake going around corners. No body roll, crisp steering response, and best of all, no tire rubbing even with back seat occupants. Vogtlands are supposed to lower the car 1", I would be surprised if it's that much.
If you are considering going for a higher-performance strut, then I would invest in the rear trailing and lateral arms as well since you already have the HD sway bars. It all comes down top how much you want to spend and where you want the handling to be. Point is that spendy struts by themselves are like leaving the window open with the a/c on...you won't get the full value of what they can do without the rest of the mods.
If it's f-it, it's a DD, then get the Excel-G and call it a day.
