Powdered Sencha and Matcha?

How does powdered Sencha compare to Matcha? I have heard that Matcha is
"bitter", although I am very interested in trying it... My idea is to
drink powdered sencha everyday, and drink matcha here and there; due to
cost. Has anyone tried both and can compare and contrast? Thanks

Well, I would imagine that the powdered sencha, imported from
Japan....would be of a different quality than the cheap green tea I'm
buying now. I do think that is a good idea though, and I may buy the
powdered sencha from O-Cha (less expensive) or from
JapaneseGreenTeaOnline (more expensive), and compare them with some
$1.50 / 48 teabags of cheap green tea (which I will grind up) from the
supermarket. Im wanting to use "powdered" because right when I wake
up, I hate waiting for the tea to steep in my impatient groggy state,
and I would also like more catcechins/vitamins/polyphenols/HEALTHiness
too.

I happened to try this powdered sencha from o-cha.com. It is clearly
not as good as matcha (becomes quite bitter and unpleasant if you put
too much, and has a rougher taste overall), but I found it a very good
(inexpensive) solution to regular drink in the office.

Being inferiour to any matcha I tried (the cheapest of which was twice
as expensive as this powerdered sencha), it still tastes much better
than green teas in bags. It is very easy to prepare: it doesn't
dissolve fully, but it make very nice and naturally tasting tea
directly in your cup - not everybody can afford teapots at their
working place.

That's my impression.
