Beast wars is a very good one to watch, I actually finished watching it in 3 days - one season per day
. My eyes were sore and at times my neck hurts but I was happy. It's got good story line that makes it very interesting and not too flooded with so many characters that makes the series an absolute toy plugging fest. Its more about the story and there's character development.
Beast Machines.. well I like it but not on the same level as beast machines. waaaay less. its kinda anti climactic sequel to beast wars actually.
Unicron trilogy... meh. I still want to complain about the parents of those children for allowing their kids to be truant delinquents, gallivanting in a war of alien giant robots. It sucks IMO, Id rather watch beast machines.. at least there's no annoying humans who seems able to avoid being squished to death by "ruthless evil decepticons". If I were a decepticon these kids wouldve been dead less than 5 seconds flat. I also hate the transforming "sailor moon" sequences which takes about a third of the story time in most of em. we know their transformation sequence after the umpteenth time its shown already , get on with the story! Oh and from what griffin has summarized before seriously many loopholes in the storylines and continuity.
Animated - would be next to Beast wars for me. It gets better as the series got older. Sure plenty of hit and miss but at least the annoying human turns out to be only semi human (oops erm spoiler?!?
)
Japanese series G1 does have plenty of boring episodes, especially headmasters, I admit I kinda fast forwarded a couple of episodes when I watch em but since i watched them in Star TV before , its more of nostalgia watching for me, I dont need to go thru all of em just the pivotal episodes to get the whole plotline to the end... it gets better in the last episodes, kinda. I watched it in Jap with eng subs coz I sometimes end up laughing while watching it in dubbed, since I can tell that theres like 3 people dubbing it trying to change their voice with each character and failing miserably

Watching it 1 episode a day is enough indeed.
One series Id like to own and watch out of curio is the RiD/ Car robots but sadly it's not yet mass produced for our region I believe.You tube has only a few incomplete episodes. As far as Ive seen its interesting.... bar the Cheesy - pedo nature of Brave Maxs power hehehehehe
