Everything you said about Petal applies to Seamstress. However, the advantage of Seamstress is that you don't need to learn a mini-language.

So let's take the same content: 

Welcome back <b tal:content="user/name">Sample Username</b>,
you last logged in <i tal:content="user/last_login">Sat 23rd Aug</i>

[download]
And when you look at this in dreamweaver or a browser you'll see 
    Welcome back Sample Username, you last logged in Sat 23rd Aug

[download]

And assuming 

$h = {
  user => {
    name => "Fergal Daly"
    last_login => "Feb 22nd"
  }
}

[download]

The processed output will be 

    Welcome back Fergal Daly, you last logged in Feb 22nd

Now for the big difference

Of course TAL handles loops and conditionals etc.
Seamstress does not. Perl has loops and conditionals and sees no need for their re-invention.
The thing that takes the most getting used to is that it's a little verbose. Unfortunately this is a necessary side effect of being truly compatible with XML/HTML.
I agree with you here, but I personally could have it no other way either. Here is how seamstress would template the same thing: 
require html::welcome_form;

my $tree = html::welcome_form->new;


my $user_name = $tree->look_down('tal:content' => 'user/name');
$user_name->replace_content($hash->{user}{name});

my $last_login = $tree->look_down('tal:content' => 'user/last_login);
$last_login->replace_content($hash->{user}{last_login});

[download]

or with a loop 

for my $content (qw(name last_login)) {

 $tree->look_down('tal:content' => $content)
      ->replace_content($hash->{user}{$content});

}
