I don't know anything about either except to say I've heard of them both. I do have a few thoughts though.
1. Which one will he get the most use out of now and in the next several months/
2. Will one give him good use both now and as he grows into toddlerhood?
3. Is there one he will be interested for only a few months and then be bored?
4. Which one is most durable and will last longer? Which is the better quality item?
The point I am trying to make is that when I buy toys for infants/toddlers I try to evaluate toys based on how long they will last, if they will span more than one developmental age/stage and will the toy actively keep my child's interest for a long time. I don't like toys that last only a month or two, or are cheap plastic and will break easily. I'd also love to throw in some educational value as well.
I don't know if this really helps or not, but it's just my 2 cents worth as former preschool teacher.
Good luck whatever you choose!
