I have the Maha 9000 and there are also a lot of fans for the LaCrosse. Either one will do a great job of charging.
What they are really good at are for those of us who are battery-geeks, and like to test real battery capacity, and do things like mate those cells that are very close to each other spec-wise to create a "pack" where we try to keep the cells dedicated to one device. They can also bring bad cells back to life, but for many this is just a lab experiment, as bad cells rejuvinated might be fun, but just starting out with good cells, and keeping them that way with good charging techniques may be more practical. The advanced features of the higher-end Maha and LaCross chargers will tell you this not only from outright failure, but from statistical analysis over the long run.
While the Maha 9000 has a simple "just drop it in" and charge mode, you may be wasting your money on testing features that you aren't going to use, or be time-consuming to operate. If that is the case, then something like the simpler Maha MH-C800S might suffice.
